Objectives Identify MRE features of colonic strictures in children/young adults with Crohn's disease. Methods Included 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. Results All 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. Conclusion Strictures on MRE did not always agree with colonoscopy, but when correlating with surgery, MRE findings were all concordant.
