- Cardiac implantable electronic devices (CIED) not an absolute contraindication to MRI Conventional cardiac implantable electronic devices (CIED) are presently not an absolute contraindication to magnetic resonance imaging (MRI), which thus is accessible for device patients depending on risk/benefit assessments. While current literature suggests that MRI can be performed without risk if precautions are taken, adverse events have been reported. The number of MR conditional CIEDs is rapidly increasing, and depending on device and electrode combinations, patients can now undergo advanced MRI at 3.0 T without risk, possibly with restriction, e.g. anatomy coverage. This article describes published guidelines, recommendations and complications that may appear during MRI and precautions to avoid and manage them. The recommendations made are based on a thorough literature review and our own experiences reported with the aim to increase the awareness of healthcare professionals so that device patients no longer are excluded from the advantages of MRI as a diagnostic tool.

- In January 2004, Per Hall et al in an article in British Medical Journal stated that children under the age of 18 months, who underwent CT of the brain, could get negative effects on cognitive abilities in adulthood. At the Department of Radiology, Lund University Hospital, 55 children under the age of 18 months underwent CT of the brain during 2004 compared to 70 children in 2003. MRI of the brain in the same age group increased in number from 52 in 2003, to 63 in 2004. CT of the brain after head trauma decreased with almost 50 % in 2004, compared to 2003. MRI is now the modality of choice for elective radiological evaluation of the brain in small children. However, CT is recommended as an emergency examination in head trauma to obtain a diagnosis without delay and to enable detection of child abuse. If the child already has undergone one or several CT examinations of the brain, MRI should be preferred to avoid further exposure to ionizing radiation. Optimization of radiation dose levels for CT of the brain in children is needed.

MR-undersökning av hjärnan vid 3 tesla. Högre magnetfältsstyrka ger bättre morfologisk och funktionell bild

- 3T MRI offers improved morphological and functional studies of the brain compared with the more commonly used field strength 1.5T. Clinical 3T MRI of the brain is beneficial for high resolution morphological imaging, MR angiography, diffusion-MRI including diffusion tensor imaging, perfusion-MRI, functional MRI (fMRI), and MR spectroscopy. The performance is enhanced by the combination with powerful magnetic field gradients.

Endovaskulär teknik vid aortaaneurysm. Lovande alternativ till öppen kirurgi

- The article consists in a presentation of endovascular surgery for abdominal aortic aneurysm repair in 23 cases. Two cases required conversion to open surgery, but the procedure could be completed in the remaining 21 cases, with a current duration of follow-up of up to 30 months. There was early leakage in one case, and late leakage in five cases. Late conversion has been necessary in three instances, and supplementary endovascular measures have been required in a further two instances. All complications have occurred in those cases operated during the first half of the study period. Modification of the endoprosthesis used and increasing skill have reduced both operation time and the complication rate. Intensive care is no longer required, and the median duration of hospitalisation is three days. Follow-up with magnetic resonance imaging has yielded new and important information.

- Assessment of neurologic prognosis after cardiac arrest. Updated recommendations from the Swedish CPR Council Expert Group European Resuscitation Council (ERC) issued updated guidelines for postresuscitation care in 2015. This paper provides updated Swedish recommendations for neurological prognostication of patients remaining unconscious after cardiac arrest (CA). The prognostication should be based on independent methods; clinical and neurophysiological examinations, imaging and biomarkers. It should not be performed earlier than three days after CA and any influence from sedatives must be negligible. Bilateral absence of both corneal and pupillary reflexes and bilaterally absent Somatosensory Evoked N20 Potentials (SSEP) at 72 hours are reliable predictors of poor outcome but the ocular reflexes have limited sensitivity and SSEP has limited availability. Hence, further delay of at least 24 hours and combinations of findings from multiple methods are often needed for reliable prognostication. If firm evidence of a poor prognosis is lacking four days after CA, further expectation with repeated examinations is recommended.

Strukturell hjärnavbildning kan förbättra diagnostiken vid demens

- Ökad kunskap om demenssjukdomar leder till att de diagnostiska kriterierna förändras. Diagnostiken kan förbättras med hjälp av hjärnavbildningsfynd.Med datortomografi (DT) och magnetisk resonanstomografi (MRT) kan medial temporallobsatrofi, global cerebral atrofi och förändringar i vit substans visualiseras och kvantifieras.För att ge optimal information om dessa förändringar krävs ett strukturerat radiologiskt DT-/MR-utlåtande. Imaging Cognitive Impairment Network (ICINET) har som huvudmål att föreslå ett standardiserat MRT-protokoll och kliniska utvärderingsverktyg (visuella skattningsskalor för MRT och DT).
