目的：探讨64层 CT 冠状动脉造影对冠状动脉的可诊断率及诊断冠心病的价值。方法选择连续行64层 CT 冠状动脉造影的可疑冠心病患者80例，患者同期行冠状动脉造影检查，评价 CT 冠脉造影对冠心病的诊断价值。结果以患者为评价标准，64层 CT 的可诊断率为98．75％；以冠状动脉主要分支为评价标准，可诊断率为96．88％；以冠状动脉节段为评价标准，可诊断率为97．25％。基于患者64层螺旋 CT 冠状动脉造影诊断冠心病的敏感性为97．92％，特异性为90．32％，阴性预测值为96．55％，阳性预测值为94．00％；基于冠状动脉主要分支的敏感性为92．13％，特异性为95．93％，阴性预测值为96．80％，阳性预测值为90．11％；基于冠状动脉节段的敏感性为90．74％，特异性为98．87％，阴性预测值为99．05％，阳性预测值为89．09％。结论MSCT 冠状动脉造影可以可靠地评价冠状动脉狭窄，能够作为筛查冠心病的无创性检查方法。

Objective To assess the diagnostic accuracy of 64-slice coronary computed tomography angiog-raphy for coronary artery disease (CAD).Methods Eight patients who were suspicious CAD underwent 64-slice CT coronary angiography and invasive coronary angiography was included.The positive predictive value (PPV),negative predictive value (NPV),sensitivity and specificity of MSCT were evaluated. Results Altogether 98.75% patient,96.88% coronary arteries and 97.25% coronary segments could be di-agnosed.PPV,NPV,sensitivity and specificity based on patients for the diagnosis of CAD were 94.00%, 96.55%,97.92% and 90.32% respectively.Based on vessels they were 90.11%,96.80%,92.13% and 95.93% respectively.Based on segments they were 89.09%,99.05%,90.74% and 98.87% respectively. Conclusion MSCT could be a non-invasive tool to evaluate CAD.
