ABSTRACT
Chest X-ray is the most common and widely used diagnostic procedure. Chest X-ray is frequently performed not only due to lungs diseases but also in other organs' diseases which indirectly affects lungs. At present computer tomography (CT) which has high resolution becomes to be more and more important. As in other diagnostic method, the main aim of CT is to confirm or reject the presence of disease. During outbreak of pneumonia in town Verkhnyaya Pyshma (Sverdlovsk region), all patients with suspected legionellosis underwent chest X-ray in front and lateral views. In several cases, computer tomography was performed.

Fifty eight patients with peripheral tumor-like formations of the lung (33 with cancer and 25 with benign formations) were examined by longitudinal tomography and CT. The potentialities of the two techniques in detecting the major semeiotic signs of cancer and malignant formations were compared. The main or major signs, such as the shape of shadow and the pattern of outlines, which make it possible to differentiate benign and malignant formations, are virtually equally imaged by the two techniques. CT is superior to X-ray longitudinal tomography in revealing minor calcifications and microdestructions, hyperplastic intrathoracic lymph nodes. The significance of some symptoms for differential diagnosis calls for further clarification.

Two hundred and fifteen patients with pulmonary involvement of lobar (regional, segmental) extent were examined. The examination procedure included clinical and laboratory tests, X-ray tomographic study, and computed tomography, bronchoscopy with biopsy, cyto- and histological studies. The nosological diagnosis was established in 96.5% of cases. Differential diagnosis was found to be difficult in 3.5% of cases.

The material of 97 pulmonary resections for large caseous focuses of tuberculosis was compared to relevant x-ray and morphological evidence. Roentgenologically, caseous-necrotic foci may be stable for a long time (6-12 months) in spite of the absence of the fibrous capsule. In view of these findings, x-ray potentialities in the diagnosis of the process form and phase are considered.

A roentgenomorphographic picture was compared with gross specimens of the lungs in 104 operated on patients with peripheral harmatochondromas. Eighty three patients were followed-up roentgenologically for 2-18 years. The resultant three variants of an x-ray picture of hamartochondromas were revealed. CT investigation showed a benign process in a majority of patients, hamartochondrosarcoma was diagnosed in 36.5 per cent. Shadow size enlargement, calcifications and their increase are not signs of malignancy.

Possibilities of roentgenologic method of examination with the use of roentgenography and tomography in the diagnosis of current forms of silicotuberculosis and tuberculosis in workers of the industries highly exposed to silicosis are analysed. ++Clinico-roentgenological+ pictures of 305 patients were studied in their dynamics for the period of 3 to 10 years. Being characterized by a benign course, silicotuberculosis is most often diagnosed in persons who left their work. A follow-up at least at 6-month intervals is of great importance in assessing its activity.
