Presence of bowel wall thickening with a low mural T2 signal intensity is more suggestive of fibrotic disease. The image shows creeping fat surrounding the descending colon. T2 mural signal intensity can be graded as follows using a T2 sequence with fat sat: Fat suppression is routinely used to differentiate between mural fat depositions and mural edema. Magnetic resonance enterography (MRE) is a well-established imaging technique that is commonly used for evaluating a variety of bowel diseases, most commonly inflammatory bowel disease which is increasing in prevalence. The lesions are usually transmural, which can lead to complications like stenoses, fistulas and abscesses. Abscesses are often seen in patients with severe active Crohn's disease. MR enterography may also be used to track how well certain treatments are working and to detect any complications. The tests fail to detect some polyps and cancers.

To evaluate the efficacy of MR enterography (MRE) in patients with known or suspected Crohn's disease without the use of anti-peristaltic pharmacologic agents compared to colonoscopy and histology. Healthcare providers use MR enterography to diagnose a number of medical conditions that affect the small intestine. We compared how a non-invasive biomarker: FCP correlates with conventional diagnostic modalities: colonoscopy and MRE in the assessment of disease activity. Colonoscopy, in turn, if not painful, then a rather unpleasant diagnostic measure. The second European evidence-based Consensus on the diagnosis and management of Crohn's disease: Current management. While most patients first present with inflammation only, about two thirds of patients will develop complications within 10 years (1). MR enterography(MRE) is a non-invasive technique for the diagnosis of small bowel disorders. Abscesses are characterized by rim enhancement on post-contrast T1 images and central high signal intensity on T2 images. A fistulous track can present with a layered 'tram track' configuration or as a linear enhancing structure. The cutoff value for active disease is 7 and for severe disease is 11.

Presence of bowel wall thickening with a low mural T2 signal intensity is more suggestive of fibrotic disease. The image shows creeping fat surrounding the descending colon. T2 mural signal intensity can be graded as follows using a T2 sequence with fat sat: Fat suppression is routinely used to differentiate between mural fat depositions and mural edema. Magnetic resonance enterography (MRE) is a well-established imaging technique that is commonly used for evaluating a variety of bowel diseases, most commonly inflammatory bowel disease which is increasing in prevalence. The lesions are usually transmural, which can lead to complications like stenoses, fistulas and abscesses. Abscesses are often seen in patients with severe active Crohn's disease. MR enterography may also be used to track how well certain treatments are working and to detect any complications. The tests fail to detect some polyps and cancers.
