[X-ray-ultrasonic parallels in tumors of the stomach and intestines].

Combined clinical, radio and ultrasound investigation of 46 patients was carried out. It was shown that routine transabdominal UTS could be employed in diagnosis of gastric and intestinal tumors but mainly at more advanced stages (T3, T4). Potentialities of the method were shown to depend, to a great extent, on a tumor site, growth, type, sizes, and spreading, as well as on the resolving power of an US diagnostic apparatus. The use of a high resolution apparatus made it possible to detect tumor invasion, but topography of a tumor was difficult to define. The x-ray or endoscopic method can be used as an adjuvant method of specified diagnosis of gastric and intestinal tumors.
