title: [Possibilities of radiologic methods (ultrasonography, computed tomography) in the preoperative evaluation of intramural invasion of gastric cancer].
abstract: By analyzing the findings in 72 patients with gastric cancer, the authors show the potentialities of noninvasive techniques of radiation diagnosis (transabdominal ultrasonography (USG) and X-ray computed tomography (CT) in the preoperative evaluation of the T-stage of gastric cancer. Ultrasound and computed tomographic semiotics of intramural invasion of gastric carcinoma is made. Ultrasonography was found to have the highest specificity in detecting early-stage gastric cancers prior to computed tomography. In the authors' opinion, a complex use of the data obtained by these techniques reveals the degree of invasion of gastric carcinoma and its extent with high precision. Transabdominal USG and CT should rank with the initial methods used for diagnosing gastric cancer. Transabdominal USG should be most expediently used as an initial technique of the above studies, by taking into account its wide accessibility, easiness-to-use, and lack of radiation load.
