Gastrointestinal imaging-practical magnetic resonance imaging approach

Figure 16 Crohn’s colitis. A: Coronal T2-weighted single shot fast spin echo; B: Coronal balanced steady state free precession images; C: Coronal; D: Axial fat-suppressed post-gadolinium 3D-GRE T1-weighted images. There is a segmental uniform thickening of the transverse colon associated with submucosal edema (A and B), mucosal hyper-enhancement, and engorgement of the supplying mesenteric vessels (C and D) in keeping with active Crohn’s colitis. Also of note is the focal hyper-enhancement of the terminal ileum (C). GRE: Gradient recalled echo.
