目的探讨双源CT血管造影(dual-source CT angiography,DSCTA)在检测动脉瘤性蛛网膜下腔出血(subarachnoid hemorrhage,SAH)后脑血管痉挛(cerebral vasospasm,CVS)中的应用价值.方法对30例动脉瘤性SAH患者行DSCTA和数字减影血管造影(digital subtraction angiography,DSA)检查,对比分析二者对CVS的检测能力.结果 DSCTA在23例低危患者中检出轻度CVS7例,DSA复查发现假阳性2例；7例高危患者在不同时间段行DSCTA检查均提示中重度CVS.以DSA为金标准,DSCTA检测CVS的总体特异性为88.9％,敏感性为100％,准确性为93.1％.结论 DSCTA是一种准确、可靠的无创性检测技术,可用于SAH患者CVS的早期鉴别诊断.

Objective To investigate the application value of dual-source CT angiography (DSCTA) in detecting cerebral vasospasm (CVS) after aneurysmal subarachnoid hemorrhage (SAH).Methods Thirty patients with aneurysmal SAH were performed DSCTA and digital subtraction angiography (DSA).The detection capabilities of both were compared and analyzed.Results DSCTA detected mild CVS in 7 patients among 23 low-risk patients.DSA re-examination found 2 false-positivc patients.DSCTA examination revealed moderate to sever CVS in 7 high-risk patients at different time periods.DSA was regarded as a gold standard,the overall specificity,sensitivity,and accuracy of DSCTA in the detection of CVS were 88.9％,100％,and 93.15％,respectively.Conclusions DSCTA is an accurate,reliable,and noninvasive detection technology.It can be used in the early differential diagnosis of CVS in patients with SAH.
