Comparative Study[Spiral computed tomography in the diagnosis of ankle and foot injuries].
The data on 187 patients with traumatic lesions of the ankle joint and foot were used to analyze the capacities of computed tomography (CT) in the diagnosis of this pathology. The efficiency of CT versus X-ray study was evaluated. ⋯ There is evidence for that CT plays a dominant role in the diagnosis of lesions of the talus and calcaneus. Emphasis is laid on the great value of secondary multi- and three-dimensional image reconstructions.

Clinical Trial[The study of cerebral venous blood flow disturbance peculiarity in the norm and under the extravasal compression of brachiocephalic veins with the use of magnetic resonance venography and ultrasound duplex scanning].
The MR-venography of the veins and brain venous sinuses, brachiocephalic veins an internal jugular veins duplex scanning have been performed in order to study the distinctions of cerebral venous hemodynamics of healthy people and the patients with venous encephalopathy caused by the extravasal compression of the brachiocephalic veins at the neck level and the superior sections of mediastinum. It has been revealed that the blood flow reducing in transverse brain sinuses occurs not only in the case of outflow disorder in the distal sections of the venous system, but also in norm. This reducing depends on anatomic constitution of confluens sinuum and the venous angle type of brachiocephalic veins. ⋯ The distinctions of hemodynamics in case of venous obstruction in contrast to arterial obstruction have been described. It has been registered that in case of outflow trouble in one of the internal jugular veins the speed and the volume of the blood flow in it are progressively reduced depending on the duration and the manifestation of compression. All this results in narrowing of the vein diameter from the affected side, and in compensatory distention of the diameter and increase of blood flow volume in the contralateral internal jugular vein, vertebral and external jugular veins, in succession.

Comparative Study[Computed tomography in the evaluation of regional metastases of lung cancer].
The rate of metastatic spread of different groups of intrathoracic lymph nodes has been studied in depending on localization of the tumor by the nodes using CT method. 126 patients were examined with verified diagnosis of lung cancer. The central form was diagnosed in 55 (43.6%) patients, peripheral--in 71 (56.4%), a tumor was located in the upper lobe in 72 (57.1%), in the lower lobe--in 47 (37.4%), and in the middle lobe--in 7 (5.5%). ⋯ The indices of the efficiency of diagnostic imaging when using CT were analyzed as well. The analysis of data obtained has shown that CT has great possibilities in evaluation of regional metastases of lung cancer.
