摘　　要：目的以冠状动脉造影(CAG)为金标准,评价64排螺旋CT冠状动脉成像(CTA)在显示冠状动脉病变时的临床价值。方法搜集70例患者的CTA完整资料,并与两周内实施的CAG结果进行对比,对CTA显示的冠状动脉病变情况进行评估。结果在CTA显示的所有病例中,共计259支冠状动脉可用于评估,107支存在病变,101支得到CAG证实;6支由CTA显示狭窄而CAG确定为正常,另外有8例CAG确诊存在的病变,而在CTA上未能显示。CTA诊断冠状动脉病变的敏感性为92.7%,特异性为96.5%,阳性预测值为94.4%,阴性预测值为95.4%。结论CTA在显示冠状动脉病变时,具有较高的敏感性和特异性,对于病变程度的评估也比较准确,适用于临床怀疑冠心病的患者进行CAG前的筛选检查。Objective To evaluate the clinical values of 64-slice computed tomography angiography for coronary heart diseases based on conventional coronary artery angiography serving as the gold standard.Methods The results of 64-slice CTA were compared with the results of CAG implemented in a recent two-week period, and the different degrees of the coronary stenosis and pathological changes of different branches of coronary artery shown by 64-slice CTA were assessed.Results In 70 patients,259 coronary arteries were e...
