摘　　要：目的评价64层螺旋CT诊断冠状动脉粥样硬化性心脏病的临床应用价值。方法40例临床诊断或可疑冠心病患者行64层螺旋CT心电门控平扫及增强扫描,并以冠状动脉造影结果作为对照。得出64层螺旋CT冠状动脉CT血管成像(CTA)诊断冠状动脉狭窄的准确性、敏感性、特异性。结果64层螺旋CT冠状动脉血管成像用于诊断冠心病的敏感性为87.1%,特异性为67.5%,准确性为80.0%。结论①64层螺旋CT检查是一种无创、快捷的冠状动脉血管检查方法,对冠心病的诊断有较高的准确性。②与冠状动脉造影术相比,64层螺旋CT冠状动脉血管成像对冠状动脉血管狭窄程度判断仍有一定差异。Objective To evaluate the clinical application of 64-slice spiral CT in the diagnosis of coronary heart disease. Methods Forty diagnosed or suspected CHD patients were performed with 64-slice spiral CT plain scanning or enhancement sanning. The results, together with the coronary anglography, were to detect the ac- curacy, sensitivity and the specificity of the CTA. Results The sensitivity, specificity and accuracy of 64 CT coro- nary angiography in CHD was 87.1% ,67.5% and 80.0% ,respectively. Conclusion （1）The 64-slice spiral CT coronary angiography is an effective, noninvasive and simple imaging technique with high sensitivity and accuracy.It is an effective way for the diagnosis of the CHD. （2）Compared with coronary angiography, the 64-slice spiral CT coronary angiography can not predict the severity of angiostegnosis accurately.
