目的 以数字减影血管造影(DSA)为参照,比较电子计算机断层扫描血管成像(CTA)诊断脑动脉狭窄的准确性,评价其临床价值.方法 对150例1月内进行CTA和DSA检查的可疑脑血管狭窄的患者进行对比,研究CTA对脑动脉狭窄的诊断价值.结果 从所研究的总的病变部位来分析:CTA与DSA符合率为98.27％(454/462);CTA阴性而DSA阳性者为1.73％(8/462);CTA阳性而DSA阴性者为1.30％(6/462);以DSA作为“金标准”;CTA诊断脑动脉狭窄的敏感性为99.57％(460/462),特异性为98.27％(454/462),假阳性为1.32％ (6/454),假阴性为1.76％ (8/454).按不同部位分层分析:颈总动脉、颈内动脉起始段、大脑中动脉M1段、椎动脉开口、椎动脉...

Objective To explore the application of computed tomography angiography （CTA） in the diagnosis of cerebral artery stenosis and its accuracy comparing with digital substraction angiography（DSA）. Methods 150 patients with CTA and DSA , compare the 2 methods, study the accuracy of CTA in the diagnosis of cerebral artery stenosis. Results Coincidence of CTA is 98.27% （ 454/462）, CTA negative and DSA positive numbered 1.73% （8/462）, CTA positive and DSA negative numbered 1.30% （6/462）, Sensitivity of CTA in the diagnosis of cerebral artery...
