PURPOSE: To define the appearance of gastric @entity674 at magnetic resonance (MR) imaging. MATERIALS AND METHODS: Nine @entity1 with @entity677 underwent MR imaging with the following sequences: nonenhanced and @entity2287 -enhanced breath-hold, T1-weighted, spoiled gradient-recalled echo (n = 9); fat-suppressed, T2-weighted, fast spin echo (n = 9); and breathing-independent, half-Fourier rapid acquisition with relaxation enhancement (n = 6). Lesion morphology, signal intensity features, and relationships to the gastric wall and surrounding organs were retrospectively evaluated. The diagnosis of @entity677 was histologically proved in all @entity1 . RESULTS: The nine @entity5 were solitary, multilobulated, shaped irregularly, predominantly exophytic, and large (diameter range, 7-28 cm [mean, 15.8 cm]). The epicenters of all lesions were extrinsic to the stomach, and all lesions arose from the @entity356 or body. Regions of @entity39 and @entity548 were detected in all cases. Marginal definition on MR images corresponded to histologic grade: High-grade @entity5 possessed ill-defined margins, and low-grade @entity5 demonstrated more well-defined margins. Relationships to surrounding organs depicted at MR imaging corresponded well with histopathologic findings. CONCLUSION: Gastric @entity674 demonstrate characteristic MR imaging features, which correspond well with histopathologic findings. The direct multiplanar capability of MR imaging facilitates delineation of relationships of the @entity5 to the stomach and surrounding organs.
