Additionally, MRE is further improved with additional refinements in fat suppression such as multi-echo Dixon 3D GRE, DWI, and perfusion techniques. Clinical features and natural history of Crohns disease. A recent meta-analysis of CE and MRE demonstrated that CE was superior to MRE for proximal small-bowel Crohns disease.3 Additionally, multiple studies have demonstrated that CE is more sensitive than MRE for detecting small aphthous lesions.4,5,6 It is known that MRE has relatively decreased sensitivity for mild disease restricted to the superficial mucosa. Tolan DJ, Greenhalgh R, Zealley IA, Halligan S, Taylor SA.
