[X-ray diagnosis of lung cancer and its morphological variants].

The purpose of the study was to substantiate the capacities of X-ray recognition of the histological types of lung cancer and different tumor differentiation grades. The data available on 238 patients were studied; of them 169 patients were diagnosed as having primary lung cancer that was morphologically verified. In 154 patients, the tumor was not greater than 3.

[Complex radiation diagnosis of solitary metastases in the lung].

Analyzing about 1000 cases of metastatic lesion of the lung indicated that the incidence of metastases was 12.9% (117 patients). Computed tomography (CT) enhances the informative value of X-ray studies in solitary metastases.

[A kit of disposable devices for transcutaneous puncture biopsy].

A kit of disposable devices has been devised for successful and safe puncture biopsy of abnormal formations deeply located in the lung, mediastinum, liver, breast, pleura. The use of the kit provides qualitative instant diagnosis, by decreasing the cost of studies, and rules out transmission of infections (hepatitis, AIDS), implantation of tumor cells into the puncture canal tissues, and reduces the incidence of traumatic pneumothorax and bleeding.

[Urgent morphologic diagnosis of tracheal tumors in the course of roentgeno-endoscopic study].

84 tracheal tumors the correct diagnosis of which was established during roentgenoendoscopical investigation combined with urgent cytological diagnosis are reported. Cytological fast diagnosis can be considered a reliable method of morphological diagnostics.
