Gastrointestinal imaging-practical magnetic resonance imaging approach

Figure 29 Duodenal lipoma. A: Coronal T2-weighted single shot fast spin echo (SSFSE); B: Axial GRE in-phase; C: Opposed-phase T1-weighted; D: Axial fat-suppressed 3D-GRE T1-weighted images. Small, well-defined, intra-luminal, duodenal mass lesion; which demonstrates intermediately high signal on SSFSE (arrow, A), high signal intensity on the in-phase T1 weighted image (B), no drop of signal on the opposed-phase images (C), and homogenously low signal intensity on the fat-suppressed image (D) in keeping with duodenal lipoma. GRE: Gradient recalled echo.
