    • Aim: The aim of this study was to investigate whether patients with diverticulitis can be prioritised with higher urgency for a subsequent full colonic examination based upon the emergency abdominal computerised tomography (CT) at the time of presentation.Method: All patients with a diagnosis of diverticulitis hospitalized during 2006 having CT on admission and a subsequent 'clean colon' examination were reviewed. The CT was reviewed by two independent and blinded senior radiologists (A and B) for signs inconsistent with diverticulitis and suggestive of malignancy. The patients were classified on CT into group 1 (normal findings, non-tumour pathology or benign polyps < 1 cm) and group 2 (benign polyps ≥ 1 cm and cancer).Results: 93 patients were reviewed with 83 in group 1and 10 in group 2. Radiologist A suggested high priority colonic examination in 18% and 50% of groups 1 and 2, and Radiologist B in 63% and 90%. There was a statically significant inter-observer difference and also lower accuracy of Radiologist B than Radiologist A in predicting a subsequent 'clean colon' examination.Conclusion: Using an emergency acute CT scan at the time of diagnosis of diverticulitis to predict a clean colon examination for neoplasia is not reliable since there is considerable degree of inter-observer difference between rediologista.

  • Comparison between MRI and CT in prediction of peritoneal carcinomatosis index (PCI) in patients undergoing cytoreductive surgery in relation to the experience of the radiologist
  • 2015
  • Ingår i: Journal of Surgical Oncology. - : Wiley. - 0022-4790 .- 1096-9098. ; 111:6, s. 746-751
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND:To compare CT and MRI for peritoneal carcinomatosis index (PCI) assessment and to compare assessments made by the radiologist based on their experiences.METHOD AND MATERIALS:MRI and CT of abdomen and pelvis were performed on 39 prospectively followed by surgery directly. Two blinded radiologists with different experience levels evaluated PCI separately on different occasions on 19 cases initially and later on the remaining 20. The agreement between the radiologists' assessment and surgical findings in total and per site were recorded.RESULTS:Total PCI: The experienced radiologist was able to assess total tumor burden correctly on both CT and MRI (kappa = 1.0). For the inexperienced radiologist the assessment was better on CT (kappa = 0.73) compared to MRI (kappa = 0.58). Different sites: The experienced radiologist showed high agreement with kappa = 0.77 for MRI and 0.80 for CT. Corresponding figures were 0.39 and 0.60 for the inexperienced radiologist. For the second phase the agreement levels increased for the inexperienced radiologist increased to 0.80 and 0.70, respectively.CONCLUSION:CT and MRI are equal when read by experienced radiologist. CT shows better results when read by an inexperienced radiologist compared to MRI, however the results of the latter can easily be improved.
