Magnetic resonance (MR) enterography is a robust alternative to modalities utilizing ionizing radiation in evaluating small bowel and surrounding structures in children and adults. Technical advances enabling rapid relatively motion-insensitive MR sequences and protocol modifications adapted to patients’ ages and morbidities will be detailed. Image optimization improves diagnostic capabilities, further enhanced by systematic review. Image interpretation, from detection and characterization to quantification of disease burden in inflammatory bowel disease (IBD) - and increasingly other bowel disorders - will be discussed. The expanding role MR enterographic findings play as imaging biomarkers in the management of IBD will also be considered.
