[Spiral computed tomography in the diagnosis of pathology of the vascular bed].

The paper presents experience with spiral computed tomography used in the examination of 1000 patients. It analyzes the potentialities of CT angiography for the diagnosis of abnormality of the vascular bed. It is concluded that the use of the new method of X-ray contrast diagnosis is promising and expedient in clinical cardiovascular surgical care.

[Regional cerebral blood flow and the infarct volume in obstruction of the internal carotid artery in relationship to the source of the collateral circulation].

The cerebral blood flow was examined by means of Obrist's 133Xe-inhalational method, cerebral angiography, and computer-aided tomography of the head in 100 patients with occlusion of the internal carotid artery. The findings obtained have revealed a correlation between the level of the compensatory collateral blood supply of the bed of the middle cerebral artery (MCA) and the source of collateral blood circulation. The authors have demonstrated the vulnerability of the MCA bed secondary to a low level of blood supply persisting despite the functioning of all pathways of the collateral circulation.

[Tomography based on the nuclear magnetic resonance effect in neurology].

On the basis of the preliminary results of their own studies and the literature data, the authors evaluated the diagnostic possibilities of NMR tomography in some diseases involving the brain. The physical basic principles of the method and the major regimens of examination are described. NMR tomography versus computer-aided tomography was shown to be more informative in the diagnosis of pathological processes in the formations of the posterior fossa of the cranium, craniovertebral junction and also in demyelinizing diseases.
