    Dynamic single-photon emission computed tomography as a method of identification of multivessel coronary artery disease by A. V. Mochula, K. V. Zavadovsky, S. L. Andreev, Yu. B. Lishmanov

    Published 2016-11-01
    Subjects: “…objective. the aim of this study was to determine the informative value of dynamic tomoscintigraphy in detection of multivessel coronary artery disease (cad). material and methods. patients with multivessel cad (n= 16) and healthy volunteers (n= 9) underwent dynamic cardiac single photon emission computed tomography with 99mтс-mibi at rest and during pharmacological stress-test. processing of acquired results involved the formation of regions of interest from the cavity and the myocardium of the left ventricle used to create activity-time curves. coronary flow reserve index was defined as a quotient of two ratios of the mean counts from the myocardial region to the integral activity in the left ventricular cavity for the studies performed during pharmacological stress test and at rest. results. the mean values of coronary flow reserve index were 1.86 (1.59…”
