Correlation of magnetic resonance enteroclysis (MRE) and wireless capsule endoscopy (CE) in the diagnosis of small bowel lesions in Crohnʼs disease

Abstract

MRE and CE show good correlation in the detection and localization of inflammatory bowel disease. As for disease activity, MRE is inferior in the detection of superficial mucosal disease but reliably discloses the presence of severe inflammatory changes within the bowel wall and beyond, which may be underestimated from the endoscopic aspect of the mucosal surface. MRE helps to rule out severe stenoses that should be referred for immediate surgical intervention. In conclusion, both modalities are complementary and MRE should be used in more severe cases of Crohn's disease and in patients who might have involvement beyond the mucosa of the small bowel.
