Fig. 4From: Gastric heterotopic pancreas and stromal tumors smaller than 3 cm in diameter: clinical and computed tomography findingsRepresentative CT images in the venous phase of stromal tumors (white arrows). a The axial image shows a will-defined round mass in the gastric upper body with endo-luminal growth pattern. The LD/SD ratio of this lesion is 1.12 (20.14/17.85 mm). The relative enhancement ratio of HP masses to the pancreas is 0.59 (56.87/96.81 HU). b The axial image shows an ill-defined round mass in the gastric lower body with exo-luminal growth patternBack to article page
