目的探讨64层螺旋CT冠状动脉 造影与左心室功能证估一站式检查的应用 价值。方法 收集50例冠状动脉CTA患者的 影像资料，分别行冠状动脉CTA检查及左 心室功能后处理、左心功能彩超检查。比 较多层螺旋CT和超声心功图在评价左心室 功能(收缩末期容量、舒张末期容量、每 搏输出量、射血分数)方面的相关性，并 比较两种检查的总时间、总费用的差别。 结果 多层螺旋CT和超声心动图测定左心 室舒张末期容积、收缩末期容积、每搏输 出量、射血分数各数值相关性较高，ＣＴ 检查可部分替代超声心动图检查。结论 冠状动脉CTA与左心室功能评估一站式检 查能同时获得冠状动脉解剖及病变信息， 而且通过对原始数据后处理，能够评估左 心室，降低了患者的经济负担和时间成 本。

Objective Discuss clinical application value of 64 layers spiral CT coronary angiography and left ventricular function for one-stop inspection. Methods Collected 50 cases of patients with coronary artery CTA images data, coronary CTA examination and post-treatment of left ventricular function and ultrasonic cardiac function examination. Compare MSCT and ultrasound heart indicator diagrams in evaluating left ventricular function (ESV、EDV、SV、EF) of relevance, and compare the two kinds of checking the difference between the total time, total cost. Results MSCT and echocardiography to determine left ventricular end-diastolic volume, end systolic volume, each cardiac output, and ejection fraction value correlation is higher. Conclusion coronary CTA with assessment of left ventricular function one-stop examination can obtain information coronary artery anatomy and pathological changes, and through to the raw data postprocessing, able to assess the left ventricle and reduce the economic burden of patients and time cost.
