摘　　要：目的探讨128层CT与超声心动图在定量评估左心功能方面的准确性及可行性。方法对60例临床确诊或疑似冠状动脉粥样硬化性心脏病患者行128层CT冠状动脉成像和超声心动图检查,分别测得左心室收缩末期容积(ESV)、舒张末期容积(EDV)、每搏输出量(SV)值及左室射血分数(EF),并对测定结果进行统计学分析。结果 128层CT和超声心动图所测得的各组左心功能数据相关性高(r值=0.75-0.89)。结论 128层CT在左心功能定量评价方面准确、可靠,与超声心动图两种方法各指标之间相关性高。一次128层CT冠状动脉成像检查,可以同时评估冠状动脉狭窄情况和左心功能。Objective To explore the accuracy and feasibility of 128-Slice CT on evaluating the left ventricular function.Methods 60 patients with known or suspected coronary artery disease（CAD） underwent 128-slice CT and then echocardiography within 72h.The left ventricular functions which included left ventricular end systolic volume（ESV）,left ventricular end diastolic volume（EDV）,stroke volume（SV） and left ventricular ejection fraction（EF） were determined by using these two modalities.Statistical analysis including Pearson correlation coefficient was carried out.Results A strong correlation between 128-Slice CT and echocardiography（r=0.750.89） was found for all parameters.Conclusion 128-slice CT angiography of the heart is noninvasive assessment of the coronary artery,whereas the analysis of left ventricular parameters provides additional information of cardiac function without further radiation exposure or scan time.
