Gastrointestinal imaging-practical magnetic resonance imaging approach

Figure 6 Chronic Crohn’s disease. A: Coronal T2-weighted single shot fast spin echo and (B) coronal balanced steady state free precession (bSSFP), images as well as coronal fat-suppressed post-gadolinium 3D-GRE T1-weighted images during the (C) arterial and (D) interstitial phases. There is an intermediately low T2 signal intensity bowel wall thickening involving the distal ileum (A), also well-appreciated on bSSFP image (B), showing negligible enhancement on post-gadolinium images (arrows, C and D), consistent with chronic fibrotic segment without superimposed inflammation. A pre-stenotic dilatation is observed. GRE: Gradient recalled echo.
