Gastrointestinal imaging-practical magnetic resonance imaging approach

Figure 22 Metastatic malignant gastric gastrointestinal stromal tumors. A: Coronal T2-weighted single shot fast spin echo (SSFSE); B: Axial fat suppressed T2-weighted SSFSE; C: Pre- and post-gadolinium 3D-GRE T1-weighted images during the (D) arterial and (E) interstitial phases. There is a hyperintense mass within the wall of the gastric antrum, which abuts the edge of the left lobe of the liver; Central necrosis is seen (arrowheads, A and B). Multiple liver lesions show heterogeneously increased T2 signal and hypervascular characteristics, fading to isointensity on late phase of enhancement, consistent with metastases. GRE: Gradient recalled echo.
