Magnetic Resonance Enterography (MRE): The role of imaging in the management of adult patients with Crohn's disease.

Abstract

Crohn's disease, an inflammatory bowel disease with devastating complications, often requires frequent imaging to detect active disease and its complications. Endoscopy, which is the gold standard for diagnosis, is contraindicated in come patients and has limited role in detecting deep submucosal/mesenteric disease, mid small bowel disease and intra-abdominal complications. Magnetic Resonance Enterography (MRE) has evolved as a complimentary non-invasive, radiation free, high resolution imaging modality in evaluating these patients, with clinical studies haveing shown MRE to help in the diagnosis and follow up of these patients. Its major advantage over CT Enterography is the absence of radiation.
