title: MR enterography for assessment and management of small bowel Crohn disease.
abstract: Magnetic resonance enterography (MRE) utilization has increased for the evaluation of small bowel diseases over the last several years. In addition to performing similarly to computed tomography enterography (CTE) in the evaluation of inflammatory bowel disease, MRE lacks ionizing radiation, can image the small bowel dynamically, and provides excellent soft tissue contrast resolution. This article reviews imaging protocols for MRE, normal MR imaging appearance of small bowel, and the imaging findings of small bowel Crohn disease. The importance of imaging findings for directing management in patients with small bowel Crohn disease is emphasized throughout.
