To compare the values of dual-source computed tomographic angiography (DSCTA) and digital subtraction angiography (DSA) in evaluating intracranial aneurysms in patients with nontraumatic subarachnoid hemorrhages (SAH) .
Totally 80 nontraumatic SAH patients were evaluated with both DSCTA and DSA. With the results of DSA as the gold standards, the sensitivity, specificity, and accuracy of DSCTA was calculated, and the agreement between these two modes was analyzed.
A total of 73 aneurysms were detected by DSCTA in 65 patients, 74 aneurysms were detected by DSA in 63 patients. 2 cases were false positive and 3 aneurysms were missed by DSCTA. The sensitivity, specificity and accuracy of DSCTA were 95.5%, 88.2%, and 94% on a per-patient basis and were 95.9%, 88.2%, and 94.5% on a per-aneurysm basis.
For patients with nontraumatic SAH, DSCTA and DSA have comparable abilities in detecting and displaying aneurysms.
比较双源计算机断层血管造影（DSCTA）和数字减影血管造影（DSA）在评估非创伤性蛛网膜下腔出血（SAH）患者颅内动脉瘤方面的价值。
对80例非创伤性SAH患者同时进行DSCTA和DSA检查。以DSA结果为金标准，计算DSCTA的敏感性、特异性和准确性，并分析两种检查方式之间的一致性。
DSCTA在65例患者中检测到73个动脉瘤，DSA在63例患者中检测到74个动脉瘤。DSCTA有2例假阳性，漏诊3个动脉瘤。基于患者的DSCTA敏感性、特异性和准确性分别为95.5%、88.2%和94%，基于动脉瘤的分别为95.9%、88.2%和94.5%。
对于非创伤性SAH患者，DSCTA和DSA在检测和显示动脉瘤方面具有相当的能力。
