[Potentialities of CT with densitometry in the assessment of local diffusion of esophageal cancer].

Computer-aided tomographic (CT) examination of 94 patients with esophageal cancer was carried out. Densitometric analysis of computer image of esophageal tumors making use of profile density histograms is presented for the first time. Objective graphic criteria for assessment of the depth of tumor invasion have been developed.

[X-ray diagnosis of malignant non-epithelial tumors of the lung].

The paper is devoted to analysis of the investigation and treatment of 137 patients with histologically verified lung sarcoma. X-ray was the chief method of primary detection. A classification, singling out 3 types, was developed: peripheral (82.

[Ultrasound and radiologic diagnosis of breast nodules in young women].

Mammography as a priority method of diagnosis of breast nodules in young women is of low efficacy as a result of a dense background of the breast as distinct from echography permitting the detection of abnormal lesion against this background. Altogether 126 patients with clinical manifestations of breast nodules were investigated. Apparatus methods used for investigation of 38 of them, revealed but manifestations of fibrocystic mastopathy.

[Radiodiagnosis of metastases to the upper abdominal and retroperitoneal lymph nodes].

The examination of 170 patients with cancer of the esophagus and proximal stomach made it possible to specify x-ray, ultrasonic and CT signs of cancer metastases to the upper abdomen and retroperitoneum. A scheme of radiodiagnosis of these metastases is suggested. The diagnostic value of x-ray, echography and CT was considered in relation to various lymph nodes involvement.
