Current status of nuclear cardiology in the Russian Federation

The article is devoted to the analysis of the current status of nuclear cardiology in the Russian Federation. The data on the number of facilities performing radionuclide investigations for the diagnosis and monitoring of the treatment of cardiovascular diseases, their staffing and equipment are given. The statistics of the conducted nuclear cardiology tests for 2018-2020 are given, as well as their methods, features and diagnostic significance are described

DIAGNOSTICS OF SIGNIFICANT CORONARY STENOSES IN PATIENTS WITH MYOCARDIAL PERFUSION DISORDERS BY THE DATA OF MONOFOTON EMISSION COMPUTED TOMOGRAPHY OF MYOCARDIUM USING MATHEMATIC INSTRUMENT OF ARTIFICIAL NEURONAL NETWORKS

The method described, of non-invasive diagnostics of significant coronary stenosis in patients with disordered myocardial perfusion by the data of monofoton emission computed tomography of myocardium. The method includes utilization of echocardiographic parameters — index of asynergy of the left ventricle and presence of significant mitral regurgitation. It is possible to find coronary stenosis via the presence of parameters obtained with mathematic instrument of artificial neuron nets: presence of lesion (if it is convenient to talk of the presence of lesion) or absence of lesion (if the lesion is absent). Specificity of the method was 93,6%, sensitivity — 68,8%
