Answer

The use of magnetic resonance imaging (MRI) was validated in a prospective study that compared this imaging modality to the standard Crohn’s Disease Endoscopic Index of Severity (CDEIS). [64] MRI accurately assessed intestinal wall thickness, the presence and degree of edema, and ulcers in patients with Crohn disease. This study confirmed that through relative contrast enhancement (RCE), MRI can play an essential role in predicting disease activity and severity in Crohn disease. [64] In addition, pelvic MRI has a higher sensitivity for the diagnosis of perirectal complications of Crohn disease.
