[Evaluation of the potentialities of ultrasonic sectorial scanning for calculating left ventricular volumes by the disc method].
Possibilities of estimating left-ventricular volumes on the basis of the disc method were examined, the primary data being provided by ultrasonic sectorial scanning. A simplified ventricular model for the estimation of volumetric parameters of unchanged and asymmetrically deformed hearts is described. The results of comparisons between the estimates and actual pathomorphologic measurements are presented. Methodological aspects of the investigation are discussed. A close correlation is demonstrated between the data obtained using the new technique and those obtained by the "area-length" method for ventriculography.
