Magnetic Resonance Enterography: 4 Years Experience In A Tertiary Medical Center

Background: Assessment of small intestinal disease remains a challenge for both clinicians and radiologists. Modern magnetic resonance enterography (MRE) is a non-radiation modality that can demonstrate both intestinal wall pathologies and extraluminal lesions.Objectives: To analyze the results of 213 MRE scans performed since 2005.Methods: Consecutive MRE scans performed in our academic medical center between December 2005 and November 2009 were reviewed for patients' demographic data, indications for the examination, and main imaging findings. The imaging signs recorded were mural changes, intraluminal filling defects as well as mesenteric and extraintestinal inflammatory findings.Results: During the study period 213 MRE scans were performed; 70% of them for proven or suspected Crohn's disease (CD) of the small bowel. Another indication was small bowel neoplasm (6% of the scans). Bowel wall thickening and enhancement were seen in 60% and 53% of MRE scans, respectively. Mesenteric involvement was found in 52% of the patients. Incidental extraintestinal findings were detected in 17% of the scans. In 22% of the scans there was no pathological finding.Conclusions: In our 4-year clinical experience with MRE this non-invasive and non-radiating modality proved to be a reliable technique for the evaluation and long-term follow-up of small bowel pathologies. The most common clinical indication was the evaluation of Crohn's disease. With physicians' increased awareness, the use of MRE in the evaluation of other small bowel pathologies such as neoplasm and celiac disease will increase. IMAJ2011; 13: 172-177
