摘　　要：目的:探讨冠心病诊断中多排螺旋CT冠脉成像的临床应用价值。方法:59例疑诊冠状动脉狭窄患者行多排螺旋CT检查,了解冠状动脉病变情况,同时行冠状动脉造影进行对比。结果:59例271支血管同时经多排螺旋CT和冠状动脉造影成像。多排螺旋CT发现96支冠状动脉狭窄,其中左前降46支,回旋支15支,左主干7支,右冠状动脉25支,桥支3支。冠状动脉造影检查发现91支冠状动脉狭窄,左前降支42支,回旋支16支,左主干6支,右冠状动脉23支,桥支4支。多排螺旋CT与冠状动脉造影结果相符的病变血管84支,敏感性为92%,特异性为93%,阳性预测值为88%,阴性预测值为96%。结论:在图像质量能够满足影像学评价的基础上,多排螺旋CT可作为冠状动脉狭窄的一种可靠的无创筛选检查方法,对冠心病的诊断有着重要的临床价值。Objective：To evaluate the clinical value of multislice spiral CT（MSCT） imaging in the diagnosis of coronary artery disease.Methods：Fifty-nine patients with suspected coronary artery diseases were underwent both MSCT and coronary angiography（CAG）,then the outcomes were compared.Results：Two hundred and seventy one coronary artery segments of 59 patients were evaluated by both MSCT and CAG.Ninety-six stenosis coronary arteries were found by MSCT,including 46 left anterior descending coronary arteries（LAD）,15 left circumflex coronary arteries（LCX）,7 left main coronary arteries（LM）,25 right coronary arteries（RCA） and 3 bridge coronary arteries.Ninety-one stenosis coronary arteries were found by CAG,including 42 LAD,16 LCX,6 LM,23 RCA and 4 bridge coronary arteries.There were 84 stenosis coronary artery segments,which were found by both MSCT and CAG.The global sensitivity,specificity,positive predictive value,negative predictive value of MSCT were 92%,93%,88% and 96%,respectively.Conclusion：Based on the satisfied image quality, MSCT can be a reliable noninvasive screening examination for coronary artery stenosis,it plays a great potential role in diagnosis of coronary artery disease.
