摘　　要：目的:探讨16层螺旋CT冠状动脉造影对冠状动脉病变的临床诊断价值。方法:56例疑冠状动脉病变者行16排螺旋CT检查和冠状动脉造影检查。管腔狭窄大于50%有意义,以冠状动脉造影为金标准。结果:16层螺旋CT诊断冠脉病变的灵敏度90.99%,特异度95.89%,阳性预测值90.33%,阴性预测值96.38%,准确度94.65%。结论:16层螺旋CT成像无创、简单易行,可作为冠状动脉狭窄的一种无创筛选检查方法。Objective：To evaluate the clinical value of 16-slice spiral CT angiography on diagnosis for coronary artery disease （CAD）.Methods：To select 56 patients with suspected performed 16-slice spiral CT angiography and coronary angiography, a lumen restriction of 〉50% was considered a significant stenosvasive coronary angiography was taken as gold standard coronary artery stenosis.Results：The diagnosis sensitivity was 90.99%, specificity was 95.89%, positive predictive value was 94.65%, and negative predictive value was 96.38% for 16-slice spiral CT angiography.Conclusion：As the non- intervention diagnosis method in coronary artery disease, the 16-slice spiral CT angiography is credible,can be used as a noninvasive screening method in the diagnosis of coronary artery stenosis.
