Gastrointestinal imaging-practical magnetic resonance imaging approach

Figure 9 Abscess formation complicating active Crohn’s disease. A: Coronal; B: Sagittal; C: Axial T2-weighted TSE images; D: Axial; E: Sagittal fat-suppressed post-gadolinium 3D-GRE T1-weighted images during the interstitial phase. Here is evidence of thickened small bowel loop segment and interloop mesenteric high T2 signal fluid collection (A, arrows, B and C) is noted, associated with rim enhancement (arrows, D and E) in keeping with mesenteric abscess formation complicating active Crohn’s disease. GRE: Gradient recalled echo.
