【摘要】 目的 观察左心室心肌脂肪浸润的分布特征,并分析左心室的功能。方法 回顾性分析本院用西门子双源CT进行冠状动脉CT血管造影(CTA)的图像,记录左心室心肌脂肪浸润的影像学特点和分布,并利用西门子后处理软件Syngo.via分析左心室功能。结果 共有冠状动脉CTA检查4 477例被纳入分析,其中左心室心肌脂肪浸润94例,占全部病例的2.1%,脂肪浸润主要位于心内膜下,包括左心室下壁、前壁、侧壁、后壁及室间隔下部;增强后脂肪浸润区心肌强化减低。结论 双源CT可以很好地显示左心室心肌脂肪浸润特征,并能提供左心室的功能信息。双源CT 1次扫描可以同时提供心脏形态和功能的双重信息。更多还原

【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.更多还原
