Magnetic resonance enterography (MRE) is an established test in patients with Crohn because of its ability to display transmural enteric inflammation and treatment response throughout the gastrointestinal tract without the very low potential risk of ionizing radiation. This article discusses how and when to diagnose Crohn disease with MRE (including discussion of the main differential diagnosis), how to describe the burden of enteric inflammation and its complications, and how to accurately classify disease based on interdisciplinary consensus. In addition, brief overviews of expected future MRE developments and alternative imaging modalities are also discussed.
