摘　　要：目的:研究冠状动脉狭窄诊断中双源CT定量造影的临床价值。方法:选取2013年8月-2015年12月本院收治的冠状动脉狭窄患者74例作为研究对象,对患者实施双源CT定量造影检查和冠状动脉造影检查,比较两种检查方式下冠状动脉不同狭窄程度发生概率、敏感度及特异度。结果:钙化斑块检出率为47.30%(35/74),双源CT定量造影显示轻度狭窄率为47.30%,中度狭窄率为21.62%,重度狭窄率为25.68%,闭塞率为5.41%;冠状动脉造影检查显示轻度狭窄率为40.54%,中度狭窄率为22.97%,重度狭窄率为29.73%,闭塞率为6.76%。双源CT定量造影整体诊断准确率为98.65%,轻度狭窄灵敏度和特异度分别为96.43%、93.33%,中度狭窄的灵敏度和特异度分别为88.24%、89.47%,重度狭窄的灵敏度和特异度分别为95.45%、95.65%,闭塞的灵敏度和特异度分别为100%、80.00%。结论:在冠状动脉狭窄的诊断中,对患者实施双源CT定量造影检查,准确率较高,可以对患者狭窄程度和斑块性质进行准确评估。Objective：To study the clinical diagnosis value of coronary artery stenosis in quantitative angiography with dual source CT.Method：From August 2013 to December 2015,74 cases of coronary artery stenosis in our hospital were selected as the research objects,they were underwent quantitative angiography with dual source CT and coronary angiography,the probability,sensitivity and specificity in different degree of coronary artery stenosis were compared.Result：The calcified plaque detection rate was 47.30%（35/74）,quantitative angiography with dual source CT showed that the mild stenosis rate was 47.30%,the moderate stenosis rate was 21.62%,the severe stenosis rate was 25.68%,the occlusion rate was 5.41%.Coronary angiography showed that the mild stenosis rate was 40.54%,the moderate stenosis rate was 22.97%,the severe stenosis rate was 29.73%,the occlusion rate was 6.76%.The quantitative angiography with dual source CT overall diagnostic accuracy was 98.65%,the sensitivity and specificity of mild stenosis were respectively 96.43% and 93.33%,the sensitivity and specificity of moderate stenosis were respectively 88.24% and 89.47%,the sensitivity and specificity of severe stenosis were respectively 95.45% and 95.65%,the sensitivity and specificity of occlusion were respectively 100% and 80.00%.Conclusion：In the diagnosis of coronary artery stenosis,quantitative angiography with dual source CT examination has high accuracy,it can accurately assess the degree of stenosis and the nature of the plaque.
