[Computed tomography in the diagnosis of gastric cancer].

The potentialities of x-ray computer-aided tomography (CAT) in the studies of intraparietal blastomatous infiltration are analyzed as shown by examinations of 134 patients with gastric cancer. The diagnostic efficacies of various modifications of CAT (filling of the stomach with liquid, pneumoscanning of the stomach with or without tubes) are assessed. Good diagnostic potentialities of tubal scanning of the stomach in the assessment of intraparietal tumor infiltration are demonstrated.

[Computed tomography in the diagnosis of abdominal and retroperitoneal lymphosarcomas].

Analysis of the data of 87 computer-aided tomographic examinations of patients with peritoneal and retroperitoneal lymphosarcomas permitted the authors single out a peculiar computer-tomographic "semeiotics" of this condition. Four states in computer-tomographic changes of the lymph nodes in this area were distinguished, each of them corresponding to specific clinical manifestations of the suffering. The authors came to such a conclusion as a result of detecting in the same 18 patients of a clear-cut correlation between the type of computer-tomographic semeiotics and lymphosarcoma phase in the process of therapy and after it, during remission.
