摘　　要：目的:比较256排螺旋CT与超声心动图对左心室功能的评估结果。方法:对12例冠状动脉心脏病患者,所有患者均行超声心动图和256排螺旋CT检查,观察左心室舒张末期容积(left ventricular end-diastolic volume,LVEDV)、左心室收缩末期容积(left ventricular end-systolic volume,LVESV)、每搏输出量(Left ventricular stroke volume,LVSV)、左心室射血分数(left ven-tricular ejection fraction,LVEF),并对两种方法的检测结果进行比较。结果:12例患者经超声心动图和多排螺旋CT检测的LVEDV分别为(118.5±20.8)mL、(114.6±18.5)mL;LVESV(61.3±23.3)mL、(57.9±19.2)mL;LVSV(73.8±24.6)mL、(71.6±25.1)mL;LVEF(57.7±7.6)%、(55.2±9.7)%;各项指标均差异无统计学意义(P>0.05)。但多排螺旋CT对心肌壁的厚度、心腔大小的显示均明显优于超声心动图。结论:多排螺旋CT对心脏的数据分析是建立在三维容积扫描基础上,其与超声心动图的几何假设相比,更接近心室腔的实际解剖形态,故使心肌壁的形态显示更加直观。Objective：To investigate the value of 256-slice CT in the assessment of left ventricular function.Methods：A total of 12 patients suspected with coronary heart diseases were enrolled.All patients underwent echocardiography and 256-slice spiral CT examination.The mean values of left ventricular end systolic volume（LVESV）,left ventrcular end diastolic volume（LVEDV）,left ventricular ejection fraction（EF） and stroke volume（SV） were compared.Results： All the 12 patients completed echocardiography and 256-slice spiral CT examination,and the main parameters acquired by echocardiography and 256-slice CT were LVEDV（118.5±20.8）mL,（114.6±18.5）mL;LVESV（61.3±23.3）mL,（57.9±19.2）mL;LVSV（73.8±24.6）mL,（71.6±25.1）mL;LVEF（57.7±7.6）%,（55.2±9.7）%,respectively;no differences were found between the two methods（P0.05）.However,MSCT is superior to echocardiography in the assessment of wall thickness and left ventricular chamber.Conclusions： MSCT heart analysis is based on the three-dimensional volume scan.Compared with echocardiography,it is closer to the real analytical structure of the left ventricule.
