MR imaging of the small bowel in Crohn disease

Abstract

MR enterography has an established role in evaluating patients with Crohn disease providing essential complementary information to clinical assessment, and as an indispensible adjunct to clinical tools such as colonoscopy. MR enterography examinations can establish the diagnosis of Crohn disease, evaluate disease activity and complications, and assess treatment response, thus providing support for clinical decision-making. Currently, MR imaging findings are highly predictive of tissue inflammation and can be used clinically to guide clinical care.
