Gastrointestinal imaging-practical magnetic resonance imaging approach

Figure 26 Mesenteric carcinoid. A: Coronal T2-weighted single shot fast spin echo; B: Coronal balanced steady state free precession; C and D: Coronal arterial; E: Axial enteric; F: Coronal interstitial fat-suppressed post-gadolinium 3D-GRE T1-weighted images. There is a large mesenteric mass encasing the superior mesenteric artery and its branches (arrow, B) associated with desmoplastic reaction and small bowel retraction noted on pre-contrast images (A, B), which demonstrates hypervascular (C) and typical sunburst margins (D). Liver metastases are seen with the typical wash-in (D) and washout (F) appearance mimicking the appearance of hepatocellular carcinoma. GRE: Gradient recalled echo.
