目的：应用256层螺旋CT对冠状动脉狭窄进行评估。方法：回顾性分析126例拟诊冠心病患者行256层螺旋CT （CTA）和冠状动脉造影（CAG）检查的资料。以 CAG结果为诊断冠心病的“金标准”，分析 CTA检测冠心病的准确度、灵敏度、特异度、阴性预测值与阳性预测值，并分析二者诊断冠状动脉狭窄的一致性。结果：以CAG结果为诊断冠心病的“金标准”， CTA 检测393段冠脉节段冠状动脉狭窄的准确度为89.3％，灵敏度为91.4％，特异度为84.9％，阴性预测值为82.3％，阳性预测值为92.8％，Kappa值＝0.755，P＜0.01。结论：256层螺旋CT可较好地显示冠状动脉狭窄，作为简单易行的无创性检查，对血管狭窄诊断的敏感性高。可作为亚健康人群的早期筛查和冠心病的复查可靠方法。

Objective:To assess coronary stenosis using 256-slice spiral CT (CTA).Methods:The data of 126 pa-tients diagnosed as coronary heart disease (CHD)using CTA and coronary angiography (CAG)Were retrospectively analyzed.The CAG results for CHD Were regarded as “gold standard”diagnosing CHD.The CTA diagnostic value for CHD and consistency of CAG and CTA diagnosing coronary stenosis Were analyzed.Results:A total of 393 cor-onary segments Were assessed using CTA.According to CAG results for CHD ,the CTA diagnostic accuracy Was 89.3%,sensitivity Was 91.4%,specificity Was 84.8%,negative predictive value Was 82.2% and positive predictive value Was 92.8%;the consistency of CAG and CTA diagnosing coronary stenosis Was good (Kappa value =0.755, P<0.01).Conclusion:The 256-slice spiral CT can diagnosing coronary stenosis,it possesses high sensitivity in di-agnosing vascular stenosis;as a simple and noninvasive examination it can be used as a reliable method for early screening subhealthy population and reexamine of putients With coronary heart disease.
