 This article reviews how to diagnose the invasion level of gastric carcinoma from the viewpoint of gastrography. We divide gastrographic findings into the causal findings(direct findings)and the correlational findings(indirect findings)for carcinoma invasion. In the case of depressed type cancer, to recognize causal findings such as thickness or rigidity of the gastric submucosal layer and the feature of mucosal fold are useful for diagnosing carcinoma invasion. On the other hand, in the case of protrusive type cancer it is difficult to diagnose the depth of carcinoma invasion, because the causal findings are obscured by the cancerous growth on the mucosal surface layer. In those cases we predict the carcinoma invasion by the correlational findings such as lesion size, macroscopic feature (flat elevation or dome-shaped) and histological type of the cancer. We believe that the diagnosing method of gastrography is based on the relationship between macroscopic features and pathological findings of gastric carcinomas.
