　A 61-year-old man with no subjective symptom visited our hospital for the purpose of a thorough examination of the stomach.

　In this radiologic diagnosis of the depth of can-cerous infiltration, three indications were found;

　1) Filling-defect was observed on the lesser curvature of the antrum.

　2) The margin of the depression was defined well.

　3) The mucosal elevation surrounding the depression was prominent, and partly revealed nodularity. However, all of them were not constant in Fig. 1 a, b and Fig. 2.

　It is necessary for diagnosis of the depth of cancerous infiltration in the gastric wall to observe the change of findings in various condition of stomach and in dynamic photographing.
