摘　　要：目的探讨双源CT在冠状动脉造影中的临床应用价值。方法对450例患者行双源CT冠状动脉血管造影(DSCTCA)检查,对其中76例患者同时行双源CT冠状动脉血管造影及选择性冠状动脉血管造影(CAG)检查,分析比较DSCTCA的敏感性、特异性及准确率。结果450例患者均成功完成了DSCTCA检查,并可清晰显示冠脉主干及部分分支,228例患者的747支冠脉伴有不同程度狭窄,其中76例患者的122支冠状动脉伴有重度狭窄或闭塞,以CAG为金标准,得出DSCTA的敏感性、特异性及准确率分别为100%、90.00%及94.84%,尤其对于重度狭窄及闭塞的诊断准确性达98.92%。结论双源CT对冠状动脉疾病的诊断准确率接近选择性冠状动脉造影,是一种准确可靠的检查方法。Objective To explore the clinical value of DSCT coronary angiography （DSCTCA）. Methods DSCTCA were performed in 450 patients, and 76 of 228 patients with severe stenosis underwent both DSCTCA and selective coronary angiography （CAG）, the results of DSCTCA were compared with that of CAG. Results Coronary artery branches and part subbranches were clearly displayed. One hundred and twenty-two coronary artery branches of 76 patients were diagnosed severe stenosis. In 76 cases of selective CAG, 117 branches were confirmed. The sensitivity, specificity and accuracy of DSCTCA was 100%, 90.00% and 94.84%, respectively, and the accuracy of severe stenosis was 98.92%. Conclusion Dual-source CT is a valuable method to detect and diagnose diseases of coronary artery with lower dose. The accuracy of the DSCT is approximate to the CAG in the diagnosis of coronary artery diseases.
