Magnetic resonance (MR) enterography is a targeted examination of the gastrointestinal tract, particularly the small intestine, without nasojejunal intubation (in which case it is referred to as MR enteroclysis). Until recently, MR imaging of the small bowel could not reliably compete with the high-quality small bowel images generated by computed tomography (CT). Now, however, MR enterography is not only a feasible alternative to CT, but may provide superior diagnostic information, specifically with regard to differentiating active, inflammatory disease from chronic, fibrostenotic disease. MR enterography is no longer merely adequate and radiation-free; it is an essential part of the imaging armamentarium. Copyright © 2013 Elsevier Inc. All rights reserved.
