Gastrointestinal imaging-practical magnetic resonance imaging approach

Figure 11 Imaging followup in a patient with Crohn’s disease. A and E: Coronal T2-weighted single shot fast spin echo; B and F: Coronal balanced steady state free precession images; C and G: Coronal; D and H: Axial fat-suppressed post-gadolinium 3D-GRE T1-weighted images. There is evidence of active Crohn’s disease involving a long segment of the terminal ileum (A, B, C and D) in form of diffuse wall thickening and submucosal mucosal enhancement (arrows, C and D). Four-month re-evaluation shows interval decreased wall thickening and significant decreased mucosal/serosal enhancement, consistent with favourable response to medical therapy. GRE: Gradient recalled echo.
