| 摘 要： | 目的：通过与选择性冠状动脉造影（SCA）对比,评价双源CT（DSCT）在冠状动脉狭窄患者中的应用价值,并系统分析其对不同程度冠状动脉狭窄的诊断价值.方法：52例疑似冠心病患者,男44例,女8例,平均年龄70.59岁,分别予以SCA和DSCT检查.由两位医师采用双盲法对检查结果进行比较.结果：发现DSCT对冠状动脉重度狭窄评价的敏感性为92.31%,特异性为99.82%,阳性预测值为90.57%,阴性预测值为99.32%.结论：提示DSCT可以用于判断冠状动脉狭窄情况,尤其对冠状动脉重度狭窄患者的敏感性和特异性较高,可作为冠心病患者筛查、冠状动脉手术患者术前评价和术后随访的可靠方法. |

| Abstract: | Objective:The aim of this study was to assess the diagnostic accuracy of dual-source computed tomography(DSCT) in the evaluation of coronary artery disease(CAD).Methods:Fifty-two patients(44 male,8 female,mean age 70.59) with a high pre-test probability of CAD underwent DSCT coronary angiography and selective coronary angiography(SCA).Two physicians independently assessed the images of all coronary segments.Results:The overall sensitivity,specificity,positive and negative predictive value for evaluating CAD were 92.31%,99.82%,90.57%,and 99.32%,respectively.Conclusion:The result indicates that DSCT coronary angiography provides high diagnostic accuracy for assessment of CAD.And it is a better choice for CAD evaluation. |
