 Ultrasonographic examination is being utilized more frequently as a primary screening procedure for patients with upper abdominal complaints.
 We report here of the cases in which we achieved diagnosing ultrasonographically gastric diseases such as acute gastritis, gastric ulcer and carcinoma by the real time electronic linear scanner.
 In all cases reported in this paper, sonography was performed prior to other examinations such as radiographic and endoscopic ones.
 Especially, it was very effective for patients with gastric carcinoma widely invaded through the stomach wall.
 A characteristic sonographic pattern suggesting a malignant neoplasm of the stomach is called the sign of "pseudokidney" or "bull's eye" This pattern consists of central strong echo surrounded by a sonolucent rim corresponding to thickening of the stomach wall.
 So, we are quite sure that various gastric disorders may be encountered more frequently during the abdominal sonographic studies performed prior to other examinations, if very carefully observed.
