MR Enterography of Complicated Crohn Disease: Stricturing and Penetrating Disease

Abstract

Stricturing and penetrating disease are complications of Crohn disease (CD) that significantly affect patient outcomes. Careful evaluation for such complications is critical to the interpretation of magnetic resonance enterography. This manuscript outlines the key findings related to stricturing and penetrating CD and discusses current understanding of the pathophysiology and prognosis of complicated CD based on the literature.
