　　目的评价三维CT血管造影(3D-CTA)在动脉瘤性蛛网膜下腔出血(aneurysmal subarachnoid hemorrhage，aSAH)诊断的可靠性。方法对我科2010年12月-2011年11月间192名急性蛛网膜下腔出血患者行CT血管造影检查(CTA)检查并应用3D Slicer软件进行三维重建，与数字减影血管造影(digital subtraction angiography，DSA)或术中实际情况进行对比，评价CTA在动脉瘤性蛛网膜下腔出血诊断中的可靠性。结果192例中，CTA检查出动脉瘤162例，脑血管畸形12例；另有假阴性1例，假阳性1例，均通过DSA及手术证实，3D-CTA在aSAH诊断的灵敏性为96.17%，特异性为94.11%。结论3D-CTA是动脉瘤性蛛网膜下腔出血的首选检查方法。

Objective To evaluate the reliability of 3D-CT angiography (3D-CTA) in diagnosis of aneurysmal subarachnoid hemorrhage (SAH). Methods One hundred and ninety-two patients with acute SAH who underwent CTA in our department from December 2010 to November 2012 were included in this study. Their 3D-CTA images were reconstructed with 3D Slicer software and compared with digital subtraction angiography (DSA) images or intraoperative actual situation. The reliability of CTA was assessed in diagnosis of aneurysmal SAH. Results 3D-CTA showed aneurysm in 162 patients, cerebral vascular malformation in 12 patients, false negative aneurysm in 1 patient, and false-positive aneurysm in 1 patient, which were confirmed by DSA or surgery, with a sensitivity of 96.17%and a specificity of 94.11%. Conclusion 3D-CTA is the first choice of method in diagnosis of aneurysmal SAH.
