摘　　要：目的探讨我科64排螺旋CT在脑动脉血管成像的临床应用价值。方法回顾性分析64排螺旋CT脑血管造影的影像表现44例,由诊断医师与数字减影血管造影(DSA)对比,进行图像综合评价。结果 64例患者中,60例图像显示成功,脑动脉狭窄38例(伴脑梗死12例),脑动脉瘤14例(脑动脉狭窄伴动脉瘤8例),动静脉畸形8例。与DSA相比,CT血管造影(CTA)诊断脑血管疾病的敏感性为93.75%,特异性为100%。结论 CTA与DSA的敏感性与特异性差异均无统计学意义,在临床普查、筛查上可以选用CTA成像技术。Objective To investigate angiography applied to cerebral artery clinical value of 64-slice spiral CT. Methods 64-slice spiral CT angiography imaging findings of 44 cases in our department were retrospectively analyzed, compared with DSA by a physician diagnosis, the image were comprehensively evaluated. Results In 64 patients, 60 images show the success of cerebral artery stenosis in 38 cases （12 cases with cerebral infarction）, cerebral aneurysms in 14 patients （cerebral artery stenosis and aneurysm 8 cases）,arteriovenous malformation in 8 cases. Compared with DSA, CTA diagnosis of cerebrovascular disease sensitivity was 93.75%, specificity was 100%. Conclusion There is no significant differences between CTA and DSA in sensitivity and specificity. CTA imaging technology can be selected in clinical census and screening.
