摘要
目的:探讨运用计算机断层扫描血管造影(CTA)诊断脑动脉瘤的价值。方法:对2011年1至11月本科收治的79例自发性蛛网膜下腔出血患者进行CTA检查,然后进行全脑数字减影血管造影(DSA)。以DSA为"金标准",计算CTA对脑动脉瘤诊断的敏感度和特异度。结果:本组79例患者CTA共检出46例52个动脉瘤,DSA检出48例55个动脉瘤;CTA检出非动脉瘤病灶52个,DSA检出非动脉瘤病灶56个。以DSA为"金标准",CTA对脑动脉瘤诊断的敏感度为94.5%(52/55),特异度为92.9%(52/56)。结论:使用CTA检测脑动脉瘤是一种可靠的方法。
Objective： To investigate the importance of computed tomography angiography （CTA） for diagnosis of cerebral aneurysm. Methods： From January through November 2011, 79 patients with subarachnoid hemorrhage underwent first CTA examination and then digital subtraction angiography （DSA） in our department. On the basis of the gold standard of DSA, the sensitivity and specificity of CTA in the diagnosis of cerebral aneurysm were calculated. Results：CTA detected 52 aneurysms in 46 patients in this group while DSA detected 55 aneurysms in 48 patients. The sensitivity of CTA was 94.5% （52/55） and the specificity was 92.9% （52/ 56）. Conclusion ： CTA is a reliable technique for diagnosis of cerebral aneurysm.
