Abstract

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.
