Key Points
MR enterography has become an important technique for imaging of the small bowel. Technical advances, especially fast imaging techniques, were a major impetus for this development. Luminal distension is obtained by oral intake of a contrast agent; often a biphasic contrast agent is used. This has been shown to be sufficient to demonstrate pathologic findings. The major indication for MR enterography is follow-up of disease activity in Crohn's disease. It can also be used as an alternative for endoscopy and MR enteroclysis for the work-up of patients with symptoms most likely related to small bowel diseases and for specific conditions such as lymphoma and small bowel polyps. Patient acceptance of MR enterography is high when compared to MR enteroclysis and colonoscopy, which is important for frequent application of the technique for monitoring treatment. Thereby, the technique has logistical advantages over MR enteroclysis.
