Abstract: Objective To study the distribution characteristics of myocardial fat infiltration and to analyze the function of the left ventricle (LV).Methods The images of patients who performed coronary CT angiography (CTA)in Siemens DSCT were reviewed retrospectively.The imaging characteristics and location of myocardial fat infiltration were recorded and the LV function was analyzed by Siemens Syngo.via software.Results Totally 4 477 patients were enrolled in this study.Among them,myocardial fat infiltration of the LV was found in 94 (accounting for 2.1%)patients.The fat infiltration was mainly located underlying the endocardium,including the inferior,anterior,lateral and posterior walls of the LV,as well as the inferior part of the interventricular septum.The enhancement image showed low intensity in the myocardium with fat infiltration.Conclusion The characteristics of myocardial fat infiltration can be well displayed by DSCT,as well as the LV function.DSCT can provide both morphological and functional information of the heart via one scan.
