title: Roentgen features of the superficial depressed type of early gastric carcinoma.
abstract: The superficial depressed type of early gastric carcinoma is described. The macroscopic appearance is characterized by an irregular erosion, often associated with a deeper central ulceration. The surrounding mucosal folds exhibit abrupt termination, narrowing, and clubbing. The roentgen diagnosis requires good demonstrations of detail. The double-contrast technique is most important and informative and can be used to study almost any part of the stomach.
