Abstract
ObjectivesIdentify MRE features of colonic strictures in children/young adults with Crohn's disease. MethodsIncluded are patients with colonic strictures on colonoscopy imaged with MRE. Bowel wall thickening (BWT) with luminal narrowing, pre-stenotic dilatation (PSD), bowel wall enhancement, and diffusion restriction were evaluated. ResultsAll potential strictures (n=12) had BWT with luminal narrowing on MRE. 8/12 had PSD, meeting our MRE stricture criteria. MRE diagnosed 8/12 colonic strictures compared to colonoscopy but was concordant with findings in all surgical patients. ConclusionStrictures on MRE did not always agree with colonoscopy, but when correlating with surgery, MRE findings were all concordant.
