    • The aim of this study was to assess patient-reported impacts and health-related quality of life (HRQL) of a 2-year follow-up programme in a large cohort of patients with stationary, non-functioning, adrenal incidentalomas (AIs) in western Sweden. 145 patients (mean age 68years, 62% females) with AI from a prospective study in western Sweden were studied. All had completed a 2-year follow-up programme by November 2007, without evidence of adrenal malignancy or hormone over-production. To evaluate patient-reported impacts and HRQL, an eight-item adrenal incidentaloma impact questionnaire was used retrospectively, together with the hospital anxiety and depression scale, and the short form-36. There were 111 patients (mean age 67years, 63% females) who responded to the questionnaire (response rate 77%). 77% reported that the AI diagnosis had caused them to be worried; however, fewer than 20% had thought about the lesion often during the follow-up programme, and only 3% had felt that it had a large impact on their current daily life. Only 4% stated that the follow-up programme had been a negative experience, nevertheless 10% reported a negative impact on their HRQL during the follow-up programme. Only 2% stated that release from follow-up caused worry to any degree. In total, 29% had possible anxiety, and 30% had possible depression, probably reflecting significant co-morbidity. Possible anxiety correlated with a more negative experience of the follow-up programme. In conclusion, the 2-year follow-up programme for patients with AI was well tolerated. Nonetheless, a small number remained worried throughout follow-up, suggesting the need for tailored counselling in individual patients to ameliorate negative impacts of follow-up.

  • Long-term outcome of stenting for atherosclerotic renal artery stenosis and the effect of angiographic restenosis.
  • 2018
  • Ingår i: Acta radiologica. - : SAGE Publications. - 1600-0455 .- 0284-1851. ; 59:12, s. 1438-1445

    • Background Symptomatic renal artery stenosis (RAS) is mainly treated with pharmacological blood pressure control, sometimes with percutaneous transluminal renal angioplasty (PTRA). It is unclear if PTRA benefits these patients over time. Purpose To determine long-term renal function, morbidity, and mortality in patients with symptomatic RAS treated with PTRA, and whether long-term outcomes are associated with angiographic restenosis. Material and Methods Retrospective single-center, long-term follow-up of 57 patients with atherosclerotic RAS treated with PTRA with stent during 1995-2004 and investigated for restenosis with angiography after one year. Outcomes were retrieved from medical records and from mandatory healthcare registries. Mortality rates were related to expected survival in an age- and gender-matched population, using a life-table database. Surviving patients were assessed with blood pressures, laboratory tests, duplex ultrasonography, and radioisotope renography. Results Median follow-up was 11 years 7 months. Major indications for PTRA were therapy-resistant hypertension and declining renal function. Angiographic restenosis at one year was found in 21 of 57 patients (37%). Thirty-six patients (60%) died during follow-up. Main cause of death was cardiovascular events (54%). Mortality was significantly increased, and morbidity and healthcare utilization were high. Hypertension control during follow-up was stable with persistent need for anti-hypertensive medication, and renal function remained moderately reduced with no long-term difference between patients with vs. without restenosis. Conclusion Long-term prognosis after PTRA for atherosclerotic RAS is dismal, with high mortality and morbidity and reduced renal function, despite maintained hypertension control. Restenosis does not appear to affect late outcome.

  • Survival and quality of life after renal angioplasty: a five-year follow-up study.
  • 2009
  • Ingår i: Scandinavian Journal of Urology and Nephrology. - : Informa UK Limited. - 0036-5599 .- 1651-2065. ; 43:3, s. 236-41

    • OBJECTIVE: Renal percutaneous transluminal angioplasty (PTA) treatment of renal artery stenosis has been performed worldwide since 1978, but it is still a matter of debate as to what extent the patients benefit from the procedure in terms of quality of life and long-term survival. MATERIAL AND METHODS: Of 139 patients referred for renal angioplasty owing to hypertension or pending uraemia, 105 were subsequently treated with PTA. Eighty-eight patients survived for 5 years. Fifty-nine patients were re-examined according to a protocol including physical examination, blood pressure, drug therapy, glomerular filtration rate and quality of life assessment, and an additional 29 patients were interviewed by telephone regarding quality of life. PTA was not conducted in 34 patients owing to high risks as decided at joint radiology-nephrology conferences. RESULTS: The 5-year survival was 83% for PTA-treated patients with arteriosclerotic renovascular disease, 100% for patients with fibromuscular vascular disease and 47% for the non-PTA-treated patients. The main causes of death were cardiovascular and cerebrovascular events in both groups. Reduced blood pressure and reduced need for antihypertensive drug treatment were observed in the PTA-treated patients. The renal function was stable. A majority of the PTA-treated patients stated that they had "unrestricted" physical activity, and the physical, mental and social well-being was self-rated as level 4-5 (mostly good and very good) on a five-grade scale by 53%, 67% and 75% of the patients, respectively, at the follow-up investigation. The untreated patients were not interviewed. CONCLUSION: The study showed a high survival rate, improved blood pressure control and stable renal function 5 years after renal PTA, and a vast majority of the patients rated their physical, mental and social well-being favourably.

  • The National Prostate Cancer Register in Sweden 1998-2002 : trends in incidence, treatment and survival
  • 2005
  • Ingår i: Scandinavian Journal of Urology and Nephrology. - : Informa UK Limited. - 0036-5599 .- 1651-2065. ; 39:2, s. 117-123
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVES: To provide a descriptive review of the establishment of the National Prostate Cancer Register (NPCR) in Sweden, to present clinical characteristics at diagnosis and to calculate the relative survival of different risk groups after 5 years. MATERIAL AND METHODS: Since 1998, data on all newly diagnosed prostate cancers, including TNM classification, grade of malignancy, prostate-specific antigen (PSA) level and treatment, have been prospectively collected. For the 35,223 patients diagnosed between 1998 and 2002, relative survival in different risk groups has been calculated. RESULTS: Between 1998 and 2002, 96% of all prostate cancer cases diagnosed in Sweden were registered in the NPCR. The number of new cases increased from 6137 in 1998 to 7385 in 2002. The age-standardized rate rose in those aged < 70 years, while it was stable, or possibly declining from 1999, in the older age groups. The proportion of T1c tumours increased from 14% to 28% of all recorded cases. The age-adjusted incidence of advanced tumours (M1 or PSA > 100 ng/ml) decreased by 17%. The proportion of patients receiving curative treatment doubled. Patients with N1 or M1 disease or poorly differentiated tumours (G3 or Gleason score 8-10) had a markedly reduced relative 5-year survival rate. CONCLUSIONS: It is possible to establish a nationwide prostate cancer register including basic data for assessment of the disease in the whole of Sweden. The introduction of PSA screening has increased the detection of early prostate cancer in younger men and, to a lesser extent, decreased the incidence of advanced disease. The effect of these changes on mortality is obscure but the NPCR in Sweden will serve as an important tool in such evaluation.

  • Clinical T1a Renal Cell Carcinoma, Not Always a Harmless Disease-A National Register Study
  • 2022
  • Ingår i: European Urology Open Science. - : Elsevier BV. - 2666-1691 .- 2666-1683. ; 39, s. 22-28
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: T1a renal cell carcinoma (RCC) is typically considered a curable dis-ease, irrespective of the choice of local treatment modality.& nbsp;Objective: To identify factors associated with the risk of local and distant recur-rence, and overall survival (OS) in patients with primary nonmetastatic clinical T1a RCC.& nbsp;Design, setting, and participants: A population-based nationwide register study of all 1935 patients with cT1a RCC, diagnosed during 2005-2012, identified through The National Swedish Kidney Cancer Register, was conducted.& nbsp;Outcome measurements and statistical analysis: Outcome variables were recur-rence (local or distant) and OS. Possible explanatory variables included tumor size, RCC type, T stage, surgical technique, age, and gender. Associations with disease recurrence and OS were evaluated by multivariable regression and Cox multivari-ate analyses, respectively.& nbsp;& nbsp;Results and limitations: Among 1935 patients, 938 were treated with radical nephrectomy, 738 with partial nephrectomy, and 169 with ablative treatments, while 90 patients had no surgery. Seventy-eight (4%) patients were upstaged to pT3. Local or metastatic recurrences occurred in 145 (7.5%) patients, significantly more often after ablation (17.8%). The risk of recurrence was associated with tumor size, upstaging, and ablation. Larger tumor size, disease recurrence, and older age adversely affected OS, whereas partial nephrectomy and chromophobe RCC (chRCC) were associated with improved survival. Limitations include register design and a lack of comorbidity or performance status data.& nbsp;Conclusions: Upstaging and recurrence occurred, respectively, in 4.0% and 7.5% of patients with nonmetastatic RCCs <= 4 cm. Tumor size upstaging and ablation were associated with the risk for recurrence, while tumor size and recurrence were associated with decreased OS. Patients with chRCC and partial nephrectomy had prolonged OS in a real-world setting.& nbsp;Patient summary: We studied factors that may influence the risk of disease recurrence and overall survival, in a large nationwide patient cohort having non metastatic renal cell carcinoma < 4 cm. Tumor size, tumor type, and treatment were associated with the risk of recurrence and overall death. Partial nephrectomy prolonged overall survival. (C)2022 The Author(s).

  • Predictive characteristics for disease recurrence and overall survival in non-metastatic clinical T1 renal cell carcinoma : results from the National Swedish Kidney Cancer Register
  • 2023
  • Ingår i: Scandinavian journal of urology. - : Taylor & Francis. - 2168-1805 .- 2168-1813. ; 57:1-6, s. 67-74
  • Tidskriftsartikel (refereegranskat)abstract
    • ObjectivePatients with clinical T1 renal cell carcinoma (cT1RCC) have risks for recurrence and reduced overall survival despite being in the best prognostic group. This study aimed to evaluate the association of different treatments on disease recurrence and overall survival using clinical and pathological characteristics in a nation-wide cT1RCC cohort.Materials and methodsA total of 4,965 patients, registered in the National Swedish Kidney Cancer Register (NSKCR) between 2005 and 2014, with ≥ 5-years follow-up were identified: 3,040 males and 1,925 females, mean age 65 years. Times to recurrence and overall survival were analyzed with Kaplan-Meier curves, log-rank test, and Cox regression models.ResultsAge, TNM-stage, tumor size, RCC-type, and performed treatment were all associated with disease recurrence. Patients selected for ablative treatments had increased risk for recurrent disease: hazard ratio (HR) = 3.79 [95% confidence interval (CI) = 2.69–5.32]. In multivariate analyses, age, gender, tumor size, RCC-type, N-stage, recurrence and performed treatment were all independently associated with overall survival. Patients with chRCC had a 41% better overall survival (HR = 0.59, 95% CI = 0.44–0.78; p < 0.001) than ccRCC. Patients treated with partial nephrectomy (PN) had an 18% better overall survival (HR = 0.83, 95% CI = 0.71–0.95, p < 0.001) than patients treated with radical nephrectomy.ConclusionsAge, gender, T-stage, tumor size, RCC type and treatment modality are all associated with risk of recurrence. Furthermore, age, male gender, tumor size, N-stage and recurrence are associated with reduced overall survival. Patients with chRCC, compared with ccRCC and pRCC patients, and PN compared with RN treated patients, had an advantageous overall survival, indicating a possible survival advantage of nephron sparing treatment.

  • Characteristics of timed barium esophagogram in newly diagnosed idiopathic achalasia: clinical and manometric correlates
  • 2007
  • Ingår i: Acta Radiol. - : SAGE Publications. - 0284-1851 .- 1600-0455. ; 48:1, s. 2-9
  • Tidskriftsartikel (refereegranskat)abstract
    • PURPOSE: To describe timed barium esophagogram (TBE) characteristics in patients with newly diagnosed idiopathic achalasia, and to correlate these with clinical and manometric variables. MATERIAL AND METHODS: Forty-six consecutive patients with newly diagnosed achalasia were examined with TBE. Esophageal emptying was assessed using the height, area, and volume of the barium column. Subjective evaluation was performed according to a standardized protocol in all patients. Objective diagnostic evaluation included manometry. RESULTS: At the 1-min time point after contrast ingestion, the static parameters median height, maximum, and mean width of the barium column were 16.0, 4.4, and 3.3 cm, respectively. Emptying, expressed as volume of barium, showed significant inverse correlation with the resting and the maximal relaxing pressure of the lower esophageal sphincter (LES) (R = -0.34 and R = -0.54, respectively). There was also an inverse correlation between emptied volume at TBE and the duration of symptoms (R = -0.36), and between barium column width and postprandial chest pain (R = -0.44). CONCLUSION: All patients with newly diagnosed achalasia presented with delayed emptying of barium the esophagus at TBE. The estimated emptied volume of barium (related to the ingested volume) correlated inversely with the basal tone and the relaxation pressure of the LES. Including estimation of the volume of emptied barium at TBE resulted in closer correlation with manometric values of LES tone than using the parameters traditionally recorded.

    • To choose which treatment would be most effective for the individual patient with newly diagnosed achalasia is difficult for the tending physician. A diagnostic tool that would allow prediction of the symptomatic and functional response after treatment for achalasia is therefore needed. The timed barium esophagogram (TBE) is a method that allows objective assessment of esophageal emptying, but the value of TBE in the clinical management of achalasia remains to be clarified. The aim of this study was first, to assess the ability of TBE to predict symptoms and treatment failure during post-treatment follow-up. Second, to determine whether esophageal emptying as assessed by TBE differs after treatment with pneumatic dilatation or laparoscopic myotomy. Fifty-one patients with newly diagnosed achalasia were prospectively randomized to pneumatic dilatation (n = 26) or laparoscopic myotomy (n = 25). Evaluation with TBE was performed before (n = 46) and after treatment (n = 43). The median interval between treatment and post-treatment TBE was 6 months, and the median follow-up time after the post-treatment TBE was 18 months. Following therapeutic intervention, TBE parameters did not differ significantly between treatment groups. However, significant correlations were found between the height of the barium column at 1 min and the symptom scores at the end of follow up for 'dysphagia for liquids' (P < 0.05, rho = 0.47), 'chest pain' (P < 0.05, rho = 0.42), and the 'Watson dysphagia score' (P < 0.05, rho = 0.46). Patients with less than 50% improvement in this TBE-parameter (height at 1 min) post-treatment had a 40% risk of treatment failure during follow-up. In summary, pneumatic balloon dilatation and laparoscopic myotomy similarly affected esophageal function as assessed by TBE-emptying. Lack of improvement in barium-column height post-treatment was associated with an increased risk of treatment failure which should motivate close surveillance in order to detect symptomatic recurrence at an early stage.

  • MRI combined with MR cholangiopancreatography versus helical CT in the evaluation of patients with suspected periampullary tumors: a prospective comparative study
  • 2005
  • Ingår i: Acta Radiol. - : SAGE Publications. - 0284-1851. ; 46:1, s. 16-27
  • Tidskriftsartikel (refereegranskat)abstract
    • PURPOSE: To establish the diagnostic accuracy of MRI including MR cholangiopancreatography (MRCP) compared with helical CT in the differentiation of malignant and benign lesions in the periampullary region. MATERIAL AND METHODS: Fifty-one patients (27 M, 24 F, mean age 66 years, range 39-86 years) with obstructive jaundice and sonographic evidence of intra- and extrahepatic bile duct dilatation (n=31) or suspicion of periampullary tumor, based on previously performed ultrasound and/or CT examination (n=20), were studied. MRI with MRCP and helical CT were reviewed blindly under standardized conditions. Lesion status (differentiation of malignant versus benign) was rated on a 5-point diagnostic confidence scale. Reference standards for comparison were findings at surgery or laparoscopy and/ or the clinical outcome. The predictive value of imaging findings was determined with multivariate logistic regression analysis. RESULTS: The areas under the receiver operating characteristic curve were 0.96 for MRI with MRCP and 0.81 for CT (P <0.05). Multivariate analysis of eight imaging variables at MRI indicated that a stricture with malignant characteristics at MRCP was the best predictor of malignancy. CONCLUSION: MRI with MRCP was significantly more accurate than CT in differentiating between malignant and benign lesions in patients with suspected periampullary tumors, mainly due to the information obtained on the MRCP images of the biliary and pancreatic duct anatomy.

  • Computed tomography contrast enhancement pattern of the uterus in premenopausal women in relation to menstrual cycle and hormonal contraception
  • 2021
  • Ingår i: Acta Radiologica. - : SAGE Publications. - 0284-1851 .- 1600-0455. ; 62:9, s. 1257-1262
  • Tidskriftsartikel (refereegranskat)abstract
    • Background There are different types of computed tomography (CT) contrast enhancement patterns of the uterus. It is not known whether these are hormonally dependent. Purpose To assess the relationship between these patterns and the menstrual cycle in non-users of hormonal contraception, and the possible impact of hormonal contraception. Material and Methods Prospective observational study of abdominal CT scans of 53 premenopausal women of whom 28 were non-users and 25 users of hormonal contraception. The non-users were divided according to menstrual cycle phase: follicular (n = 12); ovulatory (n = 1); and luteal (n = 12). The pattern and intensity of contrast enhancement of the uterine myometrium were assessed. Results The dominant pattern of contrast enhancement of the myometrium was the diffuse homogeneous type in both non-users and users. The intensity of the enhancement measured in Hounsfield units (HU) was higher in the follicular phase (median 102, range 73-130) compared to the luteal phase in non-users (median 92, range 57-130); however this was not statistically significant (P = 0.2). The HU values observed in users (median 95, range 45-160) were at the same levels compared to those of the luteal phase in non-users. Conclusion The dominant pattern of contrast enhancement in the portal venous phase of the myometrium in fertile ages is the diffuse homogeneous type and is independent of menstrual cycle phase or the use of hormonal contraception. However, these factors seem to play a role in the intensity of contrast enhancement, with a tendency of higher HU values in the follicular phase of non-users.

  • Acute chest pain in a top soccer player due to thoracic disc herniation
  • 2009
  • Ingår i: Spine (Phila Pa 1976). - 1528-1159. ; 34:10
  • Tidskriftsartikel (refereegranskat)abstract
    • STUDY DESIGN: Case report. OBJECTIVE: An unusual and previously not reported case of upper thoracic disc herniation combined with acute chest pain, is presented. SUMMARY OF BACKGROUND DATA: Disc herniation in the thoracic spine is rare. There are only a few cases of thoracic disc herniation in top athletes presented in the literature. The clinical presentation of a thoracic disc herniation can vary widely depending on its location and morphologic characteristics. Clinically, the acute symptoms may be severe. METHODS: A 24-year-old soccer player with acute left-sided chest pain that started in the middle of a soccer game has been followed clinically and with MRI examinations for 3 years. RESULTS: MRI of the thoracic spine showed a left-sided paramedial disc herniation at T2-T3 level and the right-sided paramedial disc herniation at T3-T4 level. The player was prescribed initial rest and subsequent physical rehabilitation. He had no further symptoms during rehabilitation to full training, and could resume play and remained symptom free for the rest of the season.The following season, the player experienced a similar sudden thoracic pain episode during training. This time the chest pain was right-sided. A new MRI of the thoracic spine showed unchanged findings. The initial rehabilitation was similar to the one used in the first episode. After 15 months with no symptoms during normal life the player was allowed to increase the intensity of training gradually and after 2 years the patient played soccer at elite level again. However, 3 years later the symptoms relapsed and the player ended his career after another rehabilitation period. CONCLUSION: In conclusion, it is important to consider thoracic disc herniation as acute chest pain in athletes and that the long-term prognosis of this entity is not always good.

    • A case report.To present a previously not described rare case of intradiscal hematoma due to acute trauma in an elite tennis player.Several studies have demonstrated a high frequency of radiological changes in the spine of athletes, especially in sports with high loads on the back. Signs of disc degeneration without disc herniation have frequently been found in magnetic resonance imaging (MRI) studies of the spine of athletes. It has also been shown that radiological abnormalities of the spine in young athletes are correlated to back pain.An elite male tennis player experienced pain in the right buttock after a backhand stroke. He was successfully treated for hip problems and started to play competitive tennis, 2 weeks later. After few games, a backhand stroke again resulted in intense pain projected in the os coccyx region. At examination, there were no neurologic disturbances. At palpation over the spinal processes (Springing test) of L1-L2, the patient experienced intense pain projected to the os coccyx region.MRI examination showed an injured L1-L2 disc with fluid inside the disc with a signal similar to blood. Four additional MRI examinations were performed 2 weeks and 2 years after the injury until disc degeneration is formed. Radiograph examination before and 2 years after the injury is available.In conclusion, trauma in athletes can cause intradiscal hematoma, which probably is a new etiology for disc degeneration. Also that sudden onset of pain in the hip or the gluteal region may be caused by referred pain due to a disc lesion. Intradiscal hematoma can be visualized using MRI.

  • Back pain and degenerative abnormalities in the spine of young elite divers: a 5-year follow-up magnetic resonance imaging study
  • 2006
  • Ingår i: Knee Surg Sports Traumatol Arthrosc. - : Springer Science and Business Media LLC. - 0942-2056 .- 1433-7347. ; 14:9, s. 907-14

    • Several studies have been published on disc degeneration among young athletes in sports with great demands on the back, but few on competitive divers; however, there are no long-term follow-up studies. Twenty elite divers between 10 and 21 years of age, with the highest possible national ranking, were selected at random without knowledge of previous or present back injuries or symptoms for an MRI study of the thoraco-lumbar spine in a 5-year longitudinal study. The occurrence of MRI abnormalities and their correlation with back pain were evaluated. Eighty-nine percent of the divers had a history of back pain and the median age at the first episode of back pain was 15 years. Sixty-five percent of the divers had MRI abnormalities in the thoraco-lumbar spine already at baseline. Only one diver without abnormalities at baseline had developed abnormalities at follow-up. Deterioration of any type of abnormality was found in 9 of 17 (53%) divers. Including all disc levels in all divers, the total number of abnormalities increased by 29% at follow-up, as compared to baseline. The most common abnormalities were reduced disc signal, Schmorl's nodes, and disc height reduction. Since almost all divers had previous or present back pain, a differentiated analysis of the relationship between pain and MRI findings was not possible. However, the high frequency of both back pain and MRI changes suggests a causal relationship. In conclusion, elite divers had high frequency of back pain at young ages and they run a high risk of developing degenerative abnormalities of the thoraco-lumbar spine, probably due to injuries to the spine during the growth spurt.

  • Back pain and MRI changes in the thoraco-lumbar spine of top athletes in four different sports: a 15-year follow-up study

    • A total 71 male athletes (weight lifters, wrestlers, orienteers, and ice-hockey players) and 21 non-athletes were randomly selected, for a baseline MRI study. After 15 years all the participants at baseline were invited to take part in a follow-up examination, including a questionnaire on back pain and a follow-up MRI examination. Thirty-two athletes and all non-athletes had disc height reduction at one or several disc levels. Disc degeneration was found in more than 90% of the athletes and deterioration had occurred in 88% of the athletes, with the highest frequency in weight lifters and ice-hockey players. 78% of the athletes and 38% of the non-athletes reported previous or present history of back pain at baseline and 71 and 75%, respectively at follow-up. There was no statistically significant correlation between back pain and MRI changes. In conclusion, athletes in sports with severe or moderate demands on the back run a high risk of developing disc degeneration and other abnormalities of the spine on MRI and they report high frequency of back pain. The study confirmed our hypothesis, i.e. that most of the spinal abnormalities in athletes seem to occur during the growth spurt, since the majority of the abnormalities demonstrated at follow-up MRI after the sports career were present already at baseline. The abnormalities found at young age deteriorated to a varying degree during the 15-year follow-up, probably due to a combination of continued high load sporting activities and normal ageing. Preventive measures should be considered to avoid the development of these injuries in young athletes.

    • STUDY DESIGN: To expose functional spinal units from adolescent porcine to mechanical flexion-compression and extension-compression to failure. The biomechanical, radiologic, magnetic resonance imaging, and histologic characteristics are described. OBJECTIVES: The aim of the present study was to investigate the fracture pattern of functional spinal units from adolescent porcine lumbar spines in in vitro compression loading and bending. SUMMARY OF BACKGROUND DATA: In several studies, it has been shown that the adolescent spine, especially the vertebral growth zones, is vulnerable to trauma. A high frequency of abnormalities affecting the spine has been found among athletes participating in sports with high demands on the back. The etiology of these abnormalities is still a controversial issue. METHODS: Sixteen functional spinal units obtained from eight adolescent male pigs were used. Eight functional spinal units were exposed to flexion-compression and eight functional spinal units to extension-compression loading to failure. They were examined with plain radiography and magnetic resonance imaging before and after the loading. The functional spinal units were finally examined macroscopically and histologically. RESULTS: Fractures/separations were seen in the growth zone anteriorly and more frequently, posteriorly in functional spinal units exposed to flexion-compression. In the extension-compression group, such injuries occurred only anteriorly. Only large fractures could be seen on plain radiographs and on magnetic resonance imaging. Macroscopically, a fracture/separation could be seen in 15 cases and histologically in all 16 cases. The median angle at failure for the flexion group was 17 degrees (range, 12-19) and for the extension group 17 degrees (range, 13-19 degrees). The median ultimate compression load in the flexion-compression group was 1894 N (range, 1607-3138 N) and in the extension-compression group 1801 N (range, 1158-2368 N). CONCLUSIONS: The weakest part of the growing porcine lumbar spine, when compressed into flexion- or extension-compression, was the growth zone. The injury was more extensive in extension loading than during flexion loading. Growth zone injuries of the adolescent spine may go undetected on plain radiographs and magnetic resonance imaging.

    • BACKGROUND: Abnormalities of the intervertebral discs have been found in a high frequency among young elite athletes. Several studies have also reported that the adolescent spine, especially the vertebral growth zones, is vulnerable to trauma. However, there is incomplete knowledge regarding the injury mechanism of the growing spine. In this study, the injury patterns of the adolescent porcine spine with disc degeneration were examined. METHODS: Twenty-four male pigs were used. A degenerative disc was created by drilling a hole through the cranial endplate of a lumbar vertebra into the disc. Two months later the animals were sacrificed and the degenerative functional spinal units (segments) were harvested. The segments were divided into three groups and exposed to axial compression, flexion compression or extension compression to failure. The load and angle at failure were measured for each group. The segments were examined with magnetic resonance imaging and plain radiography before and after the loading and finally examined macroscopically and histologically. FINDINGS: The degenerated segments required considerably more compressive load to failure than non-degenerated segments. Creating a flexion injury required significantly more load than an extension injury. Fractures and/or separations of the endplates from the vertebral bodies were seen at the margins of the endplates and in the growth zone. Only severe separations and fractures could be seen on plain radiography and magnetic resonance imaging. INTERPRETATION: The weakest part of the adolescent porcine lumbar spine with experimentally-induced degeneration, when loaded in axial compression, flexion compression or extension compression, was the growth zone, and, to a lesser extent, the endplate. Degenerated discs seem to withstand higher mechanical loads than non-degenerated discs, probably due to altered stress distribution.

  • Collaboration in the Hybrid Operating Room: A Focus Group Study From the Perspective of the Nursing Staff
  • 2021
  • Ingår i: Journal of Radiology Nursing. - : Elsevier BV. - 1546-0843 .- 1555-9912. ; 40:3, s. 259-267

    • Technical advancements in the operating room setting continue, and the concept of the hybrid operating room is promoted and accepted worldwide. The hybrid setting means inclusion of radiology in the already complex environment of a traditional operating room. Collaboration in this type of environment becomes essential and investigating how the nursing staff experiences this collaboration in the hybrid operating room is needed. The aim of the study was to investigate how the nursing staff from the specialties of surgery, anesthesiology, and radiology experienced collaborating in a hybrid operating room. Explorative qualitative design was used. Five focus groups consisting of operating room nurses, operating room assistant nurses, nurse anesthetists, assistant nurse anesthetists, and radiographers were included in the study. Interviews using semistructured questions were conducted. Directive content analysis was used for the data analysis. The following categories revealed: (1) different patient safety perspectives; (2) responsibilities being shared and divided; (3) collaboration becoming better over time; (4) uneven division of labor in a strained work situation and different terms of employment; (5) lack of education and joint meetings; and (6) environmental constraints for satisfying collaboration. The nursing staff in the hybrid operating room highlighted they worked toward a common goal but prioritized their own specific tasks rather than the procedure as a whole. This, together with the uneven task distribution and unclear responsibilities, could create tension between the different staff categories, impacting procedures negatively. The results revealed the importance of proper preparation of the staff to work in the hybrid operating room. Having team building activities, common meetings, relevant training to meet educational needs, and adjusting the team composition could improve hybrid operating room collaboration and improve patient safety and outcomes. © 2021 Association for Radiologic & Imaging Nursing

  • Patients' lived experiences of waiting for and undergoing endovascular aortic repair in a hybrid operating room: A qualitative study
  • 2020
  • Ingår i: Journal of Clinical Nursing. - : Wiley. - 0962-1067 .- 1365-2702. ; 29:5-6, s. 810-820

    • Aims and objectives The overall aim of the study was to illuminate the patients' lived experiences of waiting for and undergoing an endovascular aortic repair (EVAR) in a hybrid operating room (OR). Background The hybrid OR is an example of the technological advancements within hospitals. The environmental impact on humans is well recognised but is rarely taken into account when hospitals are designed or rebuilt. The patient's experience of a hybrid OR is not earlier described. Design A qualitative design based on hermeneutic phenomenology was implemented. Methods Interviews were conducted with 18 patients. A thematic interpretation based on van Manen's approach was then used to analyse the findings. The consolidated criteria for reporting qualitative studies (COREQ) were used (Data S1). Results The following three themes emerged from the interviews: (a) being scheduled for surgery induced both anxiety and hopefulness; (b) feeling watched over and surrendering to others in the technology intense environment and (c) feeling relief but unexpected exhaustion after surgery. In the discussion, the results were additionally reflected upon out from the four lifeworld existentials: lived body, lived space, lived time and lived others. Conclusions The hybrid OR technology did not frighten the patients, but it was also not an environment that promoted or was conductive to having a dialogue with the staff. The disease and surgery brought feelings of anxiety, which was largely associated with the uncertainty of the situation. We suggest that continuity in contact with staff and patient-centred information could be solutions to further calm the patients. Relevance to clinical practice The hybrid OR environment itself did not seem to frighten the patient, but the way the high-tech environment increased the distance between the patient and the multiple staff members needs further investigation.

    • Introduction: A hybrid operating room (OR) is a surgical OR with integrated imaging equipment and the possibility to serve both open surgery and image-guided interventions. Aim: This study aimed to investigate the work processes and types of collaboration in a hybrid OR during endovascular aortic repair (EVAR). Methods: Data consisted of video recordings from nine procedures, with a total recording time of 48 hrs 39 mins. The procedures were divided into four episodes (Acts). A qualitative cross-case analysis was conducted, resulting in a typical case. The type of collaboration during specific tasks was discussed and determined based on Thylefors' team typology. Results: An extensive amount of safety activities occurred in the preparation phase (Acts 1 and 2), involving a number of staff categories. After the skin incision (Act 3), the main activities were performed by fewer staff categories, while some persons had a standby position and there were persons who were not at all involved in the procedure. Discussion: The different specialist staff in the hybrid OR worked through different types of collaboration: multi-, inter-and transprofessional. The level of needed collaboration depended on the activity performed, but it was largely multiprofessional and took place largely in separate groups of specialties: anesthesiology, surgery and radiology. Waiting time and overlapping tasks indicate that the procedures could be more efficient and safe for the patient. Conclusion: This study highlights that the three expertise specialties were required for safe treatment in the hybrid OR, but the extent of interprofessional activities was limited. Our results provide a basis for the development of more effective procedures with closer and more efficient interprofessional collaboration and reduction of overlapping roles. Considerable waiting times, traffic flow and presence of people who were not involved in the patient care are areas of further investigation. © 2019 Bazzi et al.

  • Functional and radiological evaluation of free jejunal transplant reconstructions after radical resection of hypopharyngeal or proximal esophageal cancer
  • 2007
  • Ingår i: World J Surg. - : Springer Science and Business Media LLC. - 0364-2313 .- 1432-2323. ; 31:10, s. 1988-95
  • Tidskriftsartikel (refereegranskat)abstract
    • Cancer of the pharyngoesophageal junction (PEJ) is associated with late onset of symptoms, high morbidity, and a dismal prognosis. Radical surgery with pharyngolaryngectomy and reconstruction with a free vascularized jejunal transplant has been increasingly practiced in the treatment of these patients. This strategy is not devoid of challenges, and the present study is aimed at evaluating the long-term functional outcome among patients who have undergone such surgical treatment. Ten patients (mean age 59 years) with a mean follow-up time of 54 months were included. Clinical assessment, health-related quality of life (HRQL) questionnaires, and a standardized radiography examination were used for evaluation. The Karnofsky index ranged from 60 to 90 (mean 82). Global QL scores (EORTC QLQ-C30) had a mean value of 74, and the mean scores for dysphagia-related items of the EORTC QLQ OES-18 questionnaire were within the lower range. Radiographic signs of disturbed bolus transport through the jejunal transplant were found in all patients examined despite the grading of dysphagia from 0 to 1. The Watson dysphagia score varied between 0.5 and 45.0 (mean 16.2). No correlations were found between radiographic findings and the clinical evaluations or the outcomes assessed by the HRQL questionnaires. HRQL was found to be generally good after cancer of the PEJ and jejunal transplant insertion. Most patients reported mild dysphagia. Radiologic signs of disturbed bolus passage were common, but their clinical impact seemed questionable.

  • Endovascular training with animals versus virtual reality systems: an economic analysis
  • 2008
  • Ingår i: J Vasc Interv Radiol. - : Elsevier BV. - 1051-0443. ; 19:2 Pt 1, s. 233-8
  • Tidskriftsartikel (refereegranskat)abstract
    • PURPOSE: To assess the relative costs of a virtual reality (VR) laboratory and an animal laboratory for endovascular skills training. MATERIALS AND METHODS: Cost data extracted from a previous experiment was used to perform a financial analysis according to the guidelines published by the National Institutes of Health. The analysis compared the purchase or rental of a Procedicus Vascular Interventional System Trainer to the rental of an animal laboratory. RESULTS: The VR laboratory course cost $3,434 per trainee versus $4,634 in the animal laboratory according to the purchase-versus-rental analysis. The cost ratio was 0.74 in favor of the VR laboratory. Cost ratio sensitivity analysis ranged from 0.25 in favor of the VR laboratory to 2.22 in favor of the animal laboratory. The first-year potential savings were $62,410 assuming exclusive use of the VR laboratory. The 5-year training savings totaled $390,376, excluding the $60,000 residual value of the simulator. Simulator rental reduced the course price to $1,076 per trainee and lowered the cost ratio to 0.23 in favor of the VR laboratory. Findings of sensitivity analysis ranged from 0.08 to 0.70 in favor of the VR laboratory. The first-year and 5-year potential national savings increased to $185,026 and $1,013,238, respectively. CONCLUSIONS: Although evidence remains sparse that the training of interventional skills in artificial environments translates to better performance in human procedures, there are good pedagogic grounds on which to believe that such training will become increasingly important. The present comparison of the direct costs of two such models suggests that VR training is less expensive than live animal training.

    • Background: A majority of renal tumors are incidentally detected and may therefore have been previously radiologically overlooked. Purpose: To investigate the frequency of previously radiologically overlooked renal cell carcinoma (RCC), identify tumor characteristics and imaging factors that contribute to misdiagnoses and to investigate its consequences. Material and Methods: All RCCs identified in a regional cancer registry over one year were retrieved (n = 87). All preceding radiological examinations were re-analyzed for overlooked RCCs. Results: RCCs had been previously overlooked in 18 (21%) of the 87 patients (on 26 examinations: computed tomography [CT] = 16, magnetic resonance imaging [MRI] = 5, urography = 3, ultrasound = 2) or 18 (43%) of the 42 patients who had earlier radiological examinations. Overlooked RCCs were smaller than non-overlooked RCCs (median = 23 mm; range = 10–45 mm vs. 65 mm; range = 13–207 mm) (P < 0.0001), more frequently located in upper pole, 50% vs. 26% (P = 0.0836), and more frequently homogenous, 50% vs. 9% (P = 0.0003). There was no difference in exophytic growth (60% vs. 60%) (P = 0.74). Overlooked RCCs displayed poorer visualization on CT/MRI in all image planes (axial, coronal, sagittal) compared to non-overlooked tumors (P = 0.004, P = 0.001, P < 0.0001, respectively). Overlooked tumors had interval size progression of median 12 mm (range = 0–65 mm) to clinical detection (median = 1033 days). Conclusions: RCCs are frequently overlooked at imaging in the clinical routine. Overlooked tumors were smaller and displayed poorer visualization in all image planes compared to non-overlooked tumors. Substantial delay to clinical diagnosis and variable size progression was noted. Careful attention to the kidneys in multiple image planes seems warranted, irrespective of clinical indication. © The Foundation Acta Radiologica 2019.

  • Screening for prostate cancer: evidence, ongoing trials, policies and knowledge gaps
  • 2023
  • Ingår i: BMJ Oncology. ; 2:1, s. 1-9
  • Forskningsöversikt (refereegranskat)abstract
    • Long-term screening with serum prostate-specific antigen (PSA) and systematic prostate biopsies can reduce prostate cancer mortality but leads to unacceptable overdiagnosis. Over the past decade, diagnostic methods have improved and the indolent nature of low-grade prostate cancer has been established. These advances now enable more selective detection of potentially lethal prostate cancer. This non-systematic review summarises relevant diagnostic advances, previous and ongoing screening trials, healthcare policies and important remaining knowledge gaps. Evidence synthesis and conclusions: The strong association between low serum PSA values and minimal long-term risk of prostate cancer death allows for adjusting screening intervals. Use of risk calculators, biomarkers and MRI to select men with a raised PSA value for biopsy and lesion-targeting rather than systematic prostate biopsies reduce the detection of low-grade cancer and thereby overdiagnosis. These improvements recently led the European Union to recommend its member states to evaluate the feasibility and effectiveness of organised screening programmes for prostate cancer. Nonetheless, important knowledge gaps remain such as the performance of modern diagnostic methods in long-term screening programmes and their impact on mortality. The knowledge gaps are currently being addressed in three large randomised screening trials. Population-based pilot programmes will contribute critical practical experience.

  • Minimal risk of contrast-induced kidney injury in a randomly selected cohort with mildly reduced GFR
  • 2021
  • Ingår i: European Radiology. - : Springer Science and Business Media LLC. - 0938-7994 .- 1432-1084. ; 31:5, s. 3248-3257
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives: Previous large studies of contrast-induced or post-contrast acute kidney injury (CI-AKI/PC-AKI) have been observational, and mostly retrospective, often with patients undergoing non-enhanced CT as controls. This carries risk of inclusion bias that makes the true incidence of PC-AKI hard to interpret. Our aim was to determine the incidence of PC-AKI in a large, randomly selected cohort, comparing the serum creatinine (Scr) changes after contrast medium exposure with the normal intraindividual fluctuation in Scr. Methods: In this prospective study of 1009 participants (age 50–65 years, 48% females) in the Swedish CArdioPulmonary bioImage Study (SCAPIS), with estimated glomerular filtration rate (eGFR) ≥ 50 mL/min, all received standard dose intravenous iohexol at coronary CT angiography (CCTA). Two separate pre-CCTA Scr samples and a follow-up sample 2–4 days post-CCTA were obtained. Change in Scr was statistically analyzed and stratification was used in the search of possible risk factors. Results: Median increase of Scr post-CCTA was 0–2 μmol/L. PC-AKI was observed in 12/1009 individuals (1.2%) according to the old ESUR criteria (> 25% or > 44 μmol/L Scr increase) and 2 individuals (0.2%) when using the updated ESUR criteria (≥ 50% or ≥ 27 μmol/L Scr increase). Possible risk factors (e.g., diabetes, age, eGFR, NSAID use) did not show increased risk of developing PC-AKI. The mean effect of contrast media on Scr did not exceed the intraindividual Scr fluctuation. Conclusions: Iohexol administration to a randomly selected cohort with mildly reduced eGFR is safe, and PC-AKI is very rare, occurring in only 0.2% when applying the updated ESUR criteria. Key Points: • Iohexol administration to a randomly selected cohort, 50–65 years old with mildly reduced eGFR, is safe and PC-AKI is very rare. • Applying the updated ESUR PC-AKI criteria resulted in fewer cases, 0.2% compared to 1.2% using the old ESUR criteria in this cohort with predominantly mild reduction of renal function. • The mean effect of CM on Scr did not exceed the intraindividual background fluctuation of Scr, regardless of potential risk factors, such as diabetes or NSAID use in our cohort of 1009 individuals.

  • Difficulties and possibilities in communication between referring clinicians and radiologists: perspective of clinicians
  • 2019
  • Ingår i: Journal of Multidisciplinary Healthcare. - 1178-2390. ; 12, s. 555-564
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose: To investigate modes and quality of interprofessional communication between clinicians and radiologists, and to identify difficulties and possibilities in this context, as experienced by referring clinicians. Patients and methods: Focus group interviews with 22 clinicians from different specialties were carried out. The leading question was: "How do you experience communication, verbal and nonverbal, between referring clinicians and radiologists?" Content analysis was used for interpretation of data. Results: Overall, referring clinicians expressed satisfaction with their interprofessional communication with radiologists, and digital access to image data was highly appreciated. However, increased reliance on digital communication has led to reduced face-to-face contacts between clinicians and radiologists. This seems to constitute a potential threat to bilateral feedback, joint educational opportunities, and interprofessional development. Cumbersome medical information software systems, time constraints, shortage of staff, reliance on teleradiology, and lack of uniform format of radiology reports were mentioned as problematic. Further implementation of structured reporting was considered beneficial. Conclusion: Deepened face-to-face contacts between clinicians and radiologists were considered prerequisites for mutual understanding, deepened competence and mutual trust; a key factor in interprofessional communication. Clinicians and radiologists should come together in order to secure bilateral feedback and obtain deepened knowledge of the specific needs of subspecialized clinicians.

    • Objective To study experiences of war-wounded Kurdish refugees with respect to cross-cultural communication through interpreters. Method Semi-structured interviews were conducted with ten men, aged 31–42. Content analysis was used for analysis and interpretation of data. Result War-wounded Kurdish refugees experienced a number of difficulties regarding communication through interpreters, mainly related to the insufficient language link to the Swedish authorities, particularly health care personnel. In many instances, interpreters were selected based on the immigrant's citizenship rather than mother tongue, leading to a more complex, tri-lingual interpretation situation. Differences in cultural background, fear, suspicion and lack of confidence in interpreters were addressed as other problems by the participants. Conclusion Interpreter competence and patient confidence in the interpreter are essential for an adequate cross-cultural health communication. Assignment of interpreters should be based on knowledge of the patient's/client's mother tongue, rather than citizenship, and the outcome is improved by a common ethnic and cultural background of interpreter and patient/client. Our study should be considered as a pilot study, and the results should be validated in larger cohorts as well as in other ethnic and language groups.

    • OBJECTIVE: To study a group of general practitioners' (GPs) views on cross-cultural consultations through interpreters in primary healthcare in Sweden. DESIGN: Two group interviews and three personal interviews with experienced GPs regarding clinical consultation through interpreters were carried out. The interviews were transcribed and analysed and the text was categorized according to content analysis. SETTING: Primary healthcare. SUBJECTS: Eight GPs were interviewed. MAIN OUTCOME MEASURES: The response and opinions of the GPs. RESULTS: In the analysis it appeared that an optimal clinical encounter demands an active role by all participants involved in the consultation. The interpreter has to strive after being a stable neutral information bridge, and has a balancing role between the GP and the patient. The GP has to be open to cultural inequalities and recognize consultation through an interpreter as a part of her/his job. The patient needs to be an active and visible participant, not hiding behind the interpreter. Common obstacles and imperfections to reach the best possible triad were discussed. Additionally, practical assets in the encounter were delineated. Accurate physical placing of the persons in the room, adequate length of consultation time, and using the same interpreter from one visit to another were mentioned as factors influencing the outcome of the consultation. CONCLUSION: Barriers in cross-cultural communications could originate from all persons involved, the interpreter, the GP, and the patient, as well as from tangible factors. Ways to reduce misunderstandings in GP-patient encounters through interpreters are suggested.

  • Nurse radiographers' experiences of communication with patients who do not speak the native language
  • 2010
  • Ingår i: Journal of Advanced Nursing. - 1365-2648. ; 66:4, s. 774-783
  • Tidskriftsartikel (refereegranskat)abstract
    • Aim. This paper is a report of a study exploring nurse radiographers' experiences of examining patients who do not speak the native language. Background. The increased number of immigrant patients in Western countries poses a challenge to healthcare staff, as mutual understanding is needed in encounters with patients who do not speak the language of the host country. In particular, little is known about the quality of communication in the setting of radiological examinations, i.e. short encounters with demanding technical and caring components. Methods. Three focus group interviews with experienced nurse radiographers (n = 11) were carried out in 2007. The interviews were audiotaped and transcribed. A qualitative content analysis method was applied to analyse the interview texts. Findings. Four main categories emerged in the analysis: modes, needs, quality and improvements of interpreting. The need for an interpreter is strongly associated with the type of examination. For interventional procedures and contrast-enhanced examinations, a professional interpreter is required to inform the patient and to identify and handle side effects and complications. Friends, relatives, particularly children, and staff as interpreters were not considered ideal as an alternative. Shortage of time and lack of specific knowledge about radiological procedures were identified as problems with professional interpreters. Interpreter training and checklists specific for radiology department routines were suggested, as well as improved nurse radiographers' education on intercultural communication. Conclusion. The need for an interpreter, and the native tongue of the patient, should be clearly stated on the radiology request form, to allow timely scheduling of an interpreter. Intercultural communication in nurse radiographers' education should be enhanced.

    • Improvements are needed in order to give satisfactory healthcare to patients with limited language abilities. These include improved education of interpreters, especially about cultural diversity, medical terminology and radiology methods. Early identification of the need for an interpreter, preferably stated on the radiology request form, and sufficient on-site time for radiological examinations are needed. Employment by the healthcare system of professional interpreters in the most frequent foreign languages seems warranted. Finally, inter-cultural communication skills and issues should be emphasized in nurse radiographers’ and other healthcare professionals’ educational programmes

  • Tidskriftsartikel (refereegranskat)abstract
    • PURPOSE: To determine the availability, indications, and technique of computed tomographic colonography (CTC) in Sweden and to investigate opinions on its future role in colon imaging. MATERIAL AND METHODS: In May 2004, a questionnaire on CTC was mailed to all Departments of Radiology in Sweden, and one year later a telephone interview was conducted with the departments that intended to start a CTC service. RESULTS: Ninety-nine departments (83%) answered the questionnaire, indicating that 23/ 99 (23.2%) offered a CTC service. Reasons for non-implementation of CTC were lack of CTC training in 34/73 (46.6%) and non-availability of multi-detector row CT scanners in 33/73 (45.2%), while 26% were awaiting further scientific documentation on CTC. Incomplete colonoscopy was the main indication for CTC in 21/23 (91.3%) departments performing CTC. Dual positioning, room air insufflation, and thin-slice collimation were used in all the responding departments. The number of CTC studies performed varied from 1-5 (26.1%) to more than 200 (17.4%). Intravenous contrast material was routinely administered by 9/23 (39.1%) departments. Out of 30 (39.5%) departments that in 2004 intended to start CTC, 9 (30%) had done so by June 2005. A total of 32/99 (32.3%) departments had therefore started CTC by June 2005. Half of the departments that replied believed that CTC would absolutely or probably replace barium enema in the future. CONCLUSION: The survey shows relatively limited diffusion of CTC practice in Sweden, with approximately one-third of radiology departments offering a CTC service, mostly on a small scale. A wider dissemination of CTC requires further scientific documentation of its capability, intensified educational efforts, and additional funding.

  • Computer-aided detection (CAD) as a second reader using perspective filet view at CT colonography: effect on performance of inexperienced readers.
  • 2009
  • Ingår i: Clinical Radiology. - : Elsevier BV. - 1365-229X .- 0009-9260. ; 64:10, s. 972-82
  • Tidskriftsartikel (refereegranskat)abstract
    • AIM: To evaluate whether computer-aided detection (CAD) as a second reader using perspective filet view [three-dimensional (3D) filet] improves the performance of inexperienced readers at computed tomography colonography (CTC) compared with unassisted 3D filet and unassisted two-dimensional (2D) CTC. MATERIAL AND METHODS: Fifty symptomatic patients underwent CTC and same-day colonoscopy with segmental unblinding. Two inexperienced readers read the CTC studies on 3D filet and 2D several weeks apart. Four months later, readers re-read the cases only evaluating CAD marks using 3D filet. Suspicious CAD marks not previously described on 3D filet were recorded. Jackknife free-response receiver operating characteristic (JAFROC-1) analysis was used to compare the observers' performances in detecting lesions with 3D filet, 2D and 3D filet with CAD. RESULTS: One hundred and three lesions > or =3mm were detected at colonoscopy with segmental unblinding. CAD alone had a sensitivity of 73% (75/103) at a mean false-positive rate per patient of 12.8 in supine and 11.4 in prone. For inexperienced readers sensitivities with 3D filet with CAD were 58% (60/103) and 48% (50/103) with an improvement of 14-16 percentage points (p<0.05) compared with 2D and of 10-11 percentage points (p<0.05) compared with 3D filet. For inexperienced readers, the false-positive rate was 25-41% and 71-200% higher with 3D filet with CAD compared with 3D filet and 2D, respectively. JAFROC-1 analysis showed no significant differences in per-lesion overall performance among reading modes (p=0.8). CONCLUSION: CAD applied as a second reader using 3D filet increased both sensitivity and the number of false positives by inexperienced readers compared with 3D filet and 2D, thus not improving overall performance, i.e., the ability to distinguish between lesions and non-lesions.

  • Evaluation of image quality and lesion perception by human readers on 3D CT colonography: comparison of standard and low radiation dose
  • 2010
  • Ingår i: European Radiology. - 1432-1084. ; 20:3, s. 630-9
  • Tidskriftsartikel (refereegranskat)abstract
    • AIMS: We compared the prevalence of noise-related artefacts and lesion perception on three-dimensional (3D) CT colonography (CTC) at standard and low radiation doses. METHODS: Forty-eight patients underwent CTC (64 x 0.625 mm collimation; tube rotation time 0.5 s; automatic tube current modulation: standard dose 40-160 mA, low dose 10-50 mA). Low- and standard-dose acquisitions were performed in the supine position, one after the other. The presence of artefacts (cobblestone and snow artefacts, irregularly delineated folds) and the presence of polyps were evaluated by five radiologists on 3D images at standard dose, the original low dose and a modified low dose, i.e. after manipulation of opacity on 3D. RESULTS: The mean effective dose was 3.9 +/- 1.3 mSv at standard dose and 1.03 +/- 0.4 mSv at low dose. The number of images showing cobblestone artefacts and irregularly delineated folds at original and modified low doses was significantly higher than at standard dose (P < 0.0001). Most of the artefacts on modified low-dose images were mild. No significant difference in sensitivity between the dose levels was found for polyps >/=6 mm. CONCLUSIONS: Reduction of the effective dose to 1 mSv significantly affects image quality on 3D CTC, but the perception of >/=6 mm lesions is not significantly impaired.

  • Primary three-dimensional analysis with perspective-filet view versus primary two-dimensional analysis: evaluation of lesion detection by inexperienced readers at computed tomographic colonography in symptomatic patients
  • 2009
  • Ingår i: Acta Radiologica. - : SAGE Publications. - 0284-1851 .- 1600-0455. ; 50:3, s. 244-55
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: “Perspective-filet view” is a novel three-dimensional (3D) viewing technique for computed tomography colonography (CTC). Studies with experienced readers have shown a sensitivity for perspective-filet view similar to that of 2D or 3D endoluminal fly-through in detection of colorectal lesions. It is not known whether perspective-filet view, compared to axial images, improves lesion detection by inexperienced readers. Purpose: To compare primary 3D analysis using perspective-filet view (3D Filet) with primary 2D analysis, as used by inexperienced CTC readers. Secondary aims were to compare lesion detection by 3D Filet when used by experienced and inexperienced readers, and to evaluate the effect of combined 3D Filet + 2D analysis. Material and Methods: Fifty symptomatic patients were prospectively enrolled. An experienced reader performed 3D Filet analysis followed by complete 2D analysis (3D Filet + 2D), before colonoscopy with segmental unblinding. Two inexperienced readers (readers 2 and 3), blinded to CTC and colonoscopy findings, retrospectively performed 3D Filet analysis and, after 5 weeks, 2D analysis. True positives ≥6 mm detected by the inexperienced readers with 3D Filet and/or 2D were combined to obtain 3D Filet + 2D. Results: Colonoscopy revealed 116 lesions: 16 lesions ≥10 mm, 19 lesions 6–9 mm, and 81 lesions ≤5 mm. For the experienced reader, sensitivities for lesions ≥6 mm with 3D Filet and 3D Filet + 2D were 77% and 83%, respectively. For the inexperienced readers, sensitivities for lesions ≥6 mm with 3D Filet and 2D were 51% and 57% (reader 2) and 40% and 43% (reader 3), respectively. There was no significant difference between 3D Filet and 2D regarding sensitivity and reading time. For lesions ≥6 mm, 3D Filet + 2D improved the sensitivity of reader 2 to 63% and of reader 3 to 51%. Conclusion: Lesion detection by inexperienced readers using perspective-filet view is comparable to that obtained by 2D. Lesion detection improves by combining 3D Filet + 2D, but not to the level of an experienced reader.

  • Survey update on implementation, indications, and technical performance of computed tomography colonography in Sweden
  • 2010
  • Ingår i: Acta Radiologica. - 0284-1851. ; 51:1, s. 4-8
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Computed tomographic colonography (CTC) has gained increased acceptance in the last few years as a valid substitute for double-contrast barium enema (DCBE). However, implementation of new technologies is complex, since several factors may influence the process. PURPOSE: To evaluate the current situation in Sweden concerning implementation of CTC, as compared to a previous national survey in 2005. MATERIAL AND METHODS: In December 2008, a structured, self-assessed questionnaire regarding implementation and technical performance of CTC was mailed to all radiology departments in Sweden. In March 2009, departments who had not replied were contacted by e-mail or by telephone. All (100%, 119/119) departments answered the questionnaire. RESULTS: CTC is currently performed in 50/119 (42%) departments, i.e., 18 additional departments compared to 2005. Twenty-three out of 60 (38%) responding departments stated that they intend to start to perform CTC in the near future. DCBE is currently performed in 77/119 (65%) departments, 12 departments less compared to 2005. The most common reasons for non-implementation of CTC are non-availability of spiral CT scanner (41%, 26/64) and/or multidetector-row CT scanner (39%, 25/64), and lack of doctors' time (34%, 22/64). Only 3% (2/64) of departments are "awaiting further scientific documentation" on CTC, a significant reduction compared to 2005 (P=0.002). Until 2009, 59% (29/49) of CTC centers had performed more than 200 CTCs compared to 13% (4/32) of CTC centers in 2005. Intravenous contrast material is routinely administered in 86% (42/49), and carbon dioxide is used to distend the colon in 90% (44/49). Almost all radiology departments (93%, 93/100) currently believe that CTC will "absolutely" or "probably" replace barium enema in the future, while in 2005 only 56% (55/99) gave similar answers. CONCLUSION: The survey reflects a further transition process from DCBE to CTC, with attitudes of radiologists increasingly in favor of CTC, although DCBE is still performed by the majority of radiology departments. DCBE should be replaced by colonoscopy and CTC, but the transition requires both human and economic resources.

  • Cardiac output measured by electrical velocimetry in the CT suite correlates with coronary artery enhancement: a feasibility study.
  • 2010
  • Ingår i: Acta radiologica. - : SAGE Publications. - 1600-0455 .- 0284-1851. ; 51:8, s. 895-902
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Cardiac output (CO) is inversely related to vascular contrast medium (CM) enhancement during computed tomography (CT). Impedance cardiography with a new technique, electrical velocimetry (EV), may create opportunities to measure CO pre-examination for adaptation of CM injection parameters. Purpose: To relate COEV measured by radiology staff to aortic attenuation as a measure of coronary artery attenuation during CT coronary angiography (CTCA), and to formulate a tentative statistical model to adapt CM injection parameters to CO. Material and Methods: COEV was measured immediately before 100 kVp CTCA (64-multirow detector) in 27 patients with presumed coronary artery disease. For CTCA, 260 mg I/kg (maximum dosage weight: 80/90 kg for women/men) was injected intravenously during 12 s. Simple linear regression analysis was performed to explore the correlation between aortic attenuation (Hounsfield units, HU) and body weight, the influence of COEV on aortic attenuation adjusted to injected CM dose rate (HU per mg I/kg/s), and to establish a tentative formula on how to adapt CM injection parameters to COEV and desired aortic attenuation. Results: The correlation between aortic attenuation and body weight was weak and non-significant (r=−0.14 after outlier exclusion). A significant negative correlation (r=−0.63) was found between aortic attenuation adjusted to injected CM dose rate (HU per mg I/kg/s) and COEV. The resulting formula, CM dose rate=COEV×(aortic attenuation−240)/55, made it possible to calculate CM volumes and injection rates at various COs and, for example, the present mean aortic attenuation (438 HU), injection time (12 s), CM concentration (320 mg I/ml), and a certain body weight. Conclusion: EV makes it possible to measure CO in the CT suite before vascular examinations. Hence, CM doses may be decreased in low CO states to reduce the risk of CM-induced nephropathy without jeopardizing diagnostic quality and may be increased in high CO states to avoid poor enhancement.

  • The effect of surgery on fat mass, lipid and glucose metabolism in mild primary hyperparathyroidism
  • 2018
  • Ingår i: Endocrine connections. - 2049-3614. ; 7:8, s. 941-948
  • Tidskriftsartikel (refereegranskat)abstract
    • Mild primary hyperparathyroidism has been associated with increased body fat mass and unfavorable cardiovascular risk factors.To assess the effect of parathyroidectomy on fat mass, glucose and lipid metabolism.119 patients previously randomized to observation (OBS; n=58) or parathyroidectomy (PTX; n=61) within the Scandinavian Investigation of Primary Hyperparathyroidism (SIPH) trial, an open randomized multicenter study, were included. Main outcome measures for this study were the differences in fat mass, markers for lipid and glucose metabolism between OBS and PTX 5 years after randomization.In the OBS group, total cholesterol (Total-C) decreased from mean 5.9 (±1.1) to 5.6 (±1.0)mmol/L (P=0.037) and LDL cholesterol (LDL-C) decreased from 3.7 (±1.0) to 3.3 (±0.9)mmol/L (P=0.010). In the PTX group, the Total-C and LDL-C remained unchanged resulting in a significant between-group difference over time (P=0.013 and P=0.026, respectively). This difference was driven by patients who started with lipid-lowering medication during the study period (OBS: 5; PTX: 1). There was an increase in trunk fat mass in the OBS group, but no between-group differences over time. Mean 25(OH) vitamin D increased in the PTX group (P<0.001), but did not change in the OBS group. No difference in parameters of glucose metabolism was detected.In mild PHPT, the measured metabolic and cardiovascular risk factors were not modified by PTX. Observation seems safe and cardiovascular risk reduction should not be regarded as a separate indication for parathyroidectomy based on the results from this study.

  • Adrenal lesions in patients with extra-adrenal malignancy - benign or malignant?
  • 2012
  • Ingår i: Acta oncologica. - 1651-226X. ; 51:2, s. 215-221
  • Tidskriftsartikel (refereegranskat)abstract
    • Abstract Background. Adrenal lesions in patients with extra-adrenal malignancy can be part of disseminated tumour disease, but may also be incidental, benign finding. Strict characterisation is therefore crucial, and may have profound effects on patient management. Purpose. To prospectively characterise and follow-up adrenal lesions in patients with extra-adrenal malignancy, stratified into those with past or concurrent malignancy, with or without metastases. Material and methods. All incidentally detected adrenal lesions identified at cross-sectional imaging during 18 months in a defined geographical region were prospectively reported. All adult oncologic patients with adrenal lesions were subjected to biochemical work-up and dedicated adrenal imaging for lesion characterisation, including a two year follow-up. Results. Benign adrenal lesions were found in 74% (29/39) of patients who had a history of extra-adrenal malignancy, in 53% (57/108) of those with concurrent extra-adrenal malignancy without metastatic disease and in 25% (27/109) in those with signs of metastatic disease. Conclusion. An adrenal lesion occurring in a patient with past malignancy has a high likelihood of representing a benign lesion, and even in patients with present signs of malignant disease at least one fourth to one half of such lesions are benign. Dedicated adrenal imaging including computed tomography attenuation measurements with wash-out characteristics, in addition to biochemical testing for adrenal dysfunction, is highly recommended in these cases, especially in patients without any other signs of metastatic spread.

  • Adrenal lesions: variability in attenuation over time, between scanners, and between observers.
  • 2013
  • Ingår i: Acta radiologica (Stockholm, Sweden : 1987). - : SAGE Publications. - 1600-0455 .- 0284-1851. ; 54:7, s. 817-826
  • Tidskriftsartikel (refereegranskat)abstract
    • BackgroundMeasurements of attenuation (in Hounsfield units [HU]) and contrast wash-out are widely used to characterize adrenal lesions as benign or indeterminate/malignant at computed tomography (CT). Clinical experience suggests that such measurements of adrenal lesions may vary over time and between observers, making evaluation difficult.PurposeTo investigate the change over time of adrenal lesion size, attenuation, and contrast wash-out at CT, to determine inter-observer variability, and to analyze other factors underlying the variability.Material and MethodsIn a cohort of patients, with or without malignant disease, undergoing CT, adrenal lesions were prospectively analyzed. Lesions with growth >20% or >5 mm over 6 months were excluded. Non-enhanced attenuation and contrast medium wash-out over 2-year follow-up were analyzed. An inter-observer analysis with five observers and a phantom study of eight different CT scanners were performed to assess measurement variability.ResultsMean adrenal lesion non-enhanced attenuation values decreased by 0.5 HU/year during follow-up. Using 10 HU or 40% relative wash-out as threshold values for benign versus indeterminate lesions, 27 (20%) and 39 (29%) of 136 lesions, respectively, would be reclassified at some occasion during follow-up. In the observer analysis 37 of 40 lesions demonstrated agreement between all observers, using established threshold values. The phantom study showed an intra-scanner variability of 1-3 HU, but an inter-scanner variability of up to 8 HU for water.ConclusionThe clinically widespread use of specific attenuation threshold values for characterizing adrenal lesions must be used with great caution, considering that multiple factors, related to patient, equipment, scanning technique, and observer influence the outcome.

  • Extracolonic and incidental findings on CT colonography (virtual colonoscopy)
  • 2004
  • Ingår i: AJR Am J Roentgenol. - 0361-803X. ; 182:3, s. 631-8
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: The objective of our study was to prospectively determine the frequency and clinical importance of extracolonic findings on CT colonography in symptomatic patients. SUBJECTS AND METHODS. One hundred eleven symptomatic patients referred for colonoscopy underwent CT colonography before colonoscopy. Helical CT from the diaphragm to the symphysis was performed with the patient in the supine and prone positions after rectal air insufflation. Image interpretation was done on a digital workstation. Extracolonic findings were classified as minor, moderate, or major according to potential clinical importance. Patient records, with a follow-up time of about 3 years, were reviewed to determine final diagnoses. RESULTS: Twenty-six (23%) of the patients had CT findings of major importance such as lymphadenopathy (n = 7), aortic aneurysm (n = 6), suspected solid hepatic masses (n = 5), and suspected solid renal masses (n = 4). Fifty-eight patients (52%) had findings of moderate importance such as gallstones (n = 16), indeterminate renal masses (n = 9), adrenal masses with benign appearance (n = 8), and hiatal hernia (n = 7). Forty-six patients (41%) had no or only minor findings, such as renal cysts (n = 34), renal calcifications (n = 19), and hepatic cysts (n = 14). Review of patient records showed that CT colonography contributed to the detection of major, previously unknown extracolonic disorders in 14 (13%) of the 111 patients. CONCLUSION: Potentially important extracolonic findings were revealed in 23% of the patients, leading to additional diagnostic or therapeutic considerations. Some of these findings were clinically important, whereas others were previously known or led to unnecessary workup. This finding must be taken into account when CT colonography is considered for routine diagnostic workup or screening.

  • Incidental findings on abdominal CT
  • 2017
  • Ingår i: Incidental Radiological Findings. - Cham : Springer. - 0942-5373. ; , s. 127-168
  • Bokkapitel (refereegranskat)abstract
    • Abdominal CT examinations usually cover the entire abdomen and pelvis, including all organs and tissues in the intraperitoneal, retroperitoneal, extraperitoneal/pelvic spaces, as well as the extra-abdominal soft tissues; bony structures of the spine, sacrum, pelvis, and hips; and lower part of the chest including parts of the lungs and pleural spaces. The multitude of organs and tissues involved makes abdominal CT reading complex and allows for a multitude of incidental findings that may be of degenerative, neoplastic, or other etiologies. Although scanning is sometimes limited to only the “abdomen” or only the “pelvis,” “abdominal CT” in this chapter refers to abdominal-pelvic CT, i.e., both compartments. © 2017, Springer International publishing Switzerland.
