title: Computed tomography in gastric carcinoma: thickness of gastric wall and infiltration to serosa surface.
abstract: Preoperative CT images and the operative findings from 25 patients with gastric carcinoma were comparatively studied. Infiltration of the serosa surface was noted in 84% (16 out of 19 cases) of the patients whose local thickness of the gastric wall was shown to be 1.5 cm or more on the CT images. CT images of liver metastases had an accuracy of 88% (22 cases out of 25) and a specificity of 90% (19 out of 21 cases). Regarding metastatic lymph nodes and peritoneal dissemination, the CT image gave the poor specificity.
