Clinical studies report a rate of 5% and autopsy results a rate of 25% of brain involvement in sarcoidosis. The aim of this study was to evaluate the role of radiology in the diagnosis of patients with neurosarcoidosis. The chest radiographs and MRI brain scans of 22 patients with sarcoidosis were retrospectively reviewed, along with the information that was provided in the request form and clinical charts. ⋯ Neurological signs and symptoms can be significant manifestations of sarcoidosis. Magnetic resonance imaging shows a wide spectrum of brain abnormalities associated with neurosarcoidosis. The patient's history and chest X-ray are helpful in arriving at the correct diagnosis, but in selected cases with isolated brain involvement biopsy may still be required.

Three strategies for visualisation of MR-dedicated guidewires and catheters have been proposed, namely active tracking, the technique of locally induced field inhomogeneity and passive susceptibility-based tracking. In this article the pros and cons of these techniques are discussed, including the development of MR-dedicated guidewires and catheters, scan techniques, post-processing tools, and display facilities for MR tracking. Finally, some of the results obtained with MR tracking are discussed.

We report a case in which blunt abdominal trauma resulted in injury to the mesentery with subsequent ischemic stricture of the adjacent small bowel. We present CT images at the time of trauma and 5 weeks later when clinical signs of intestinal obstruction occurred. ⋯ Histological examination of the resected segment showed mucosal and submucosal ischemia with mucosal ulceration, mural inflammation, and fibrosis. Posttraumatic intestinal stenosis subsequent to a mesenteric tear should be included in the differential diagnosis in a patient with a history of blunt abdominal trauma and signs of intestinal obstruction.

Turf battles have always existed in radiology although recently, we have observed an increase in their numbers and sometimes in their virulence. The main reasons for this increase include the relative plethora of physicians especially in industrialized areas, and the rapid progress and development of medical technology and minimally invasive techniques. ⋯ The only way that radiologists can hope to maintain control of today's techniques will be if they are willing to offer qualitative expertise in their procedures with full clinical, academic and technological backing similar, or superior to that presented by our respective clinical and surgical colleagues. Furthermore, they should be fully involved in the decisional process and actual purchase of the technological equipment of their entire institution.
