目的：探讨16层螺旋CT血管造影（ CT angiography ， CTA）对颅内动脉瘤的诊断价值。方法：对56例急诊蛛网膜下腔出血（ subarachnoid hemorrhage ，SAh）患者行头部16层螺旋CTA检查，对照数字减影血管造影（ Digital Subtraction Angiography ， DSA）结果，评估16层螺旋CTA诊断动脉瘤的准确性。结果：56例中DSA检查发现59个动脉瘤，16层螺旋CTA检查发现56个动脉瘤，CTA诊断颅内动脉瘤的敏感性为94．6％，特异性为100％，准确性95％。结论：16层螺旋CTA可获得与DSA相近的检查结果，具有较高的敏感性和特异性，快捷，无创，可代替DSA进行筛查及术前评估颅内动脉瘤。

Objective:To determine the clinical value of applying 16-slice CTA to the diagnosis of acute cerebral aneurysms .Meth-ods:56 patients with acute subarachnoid hemorrhage were diagnosed by using 16-slice CTA , Compare the result of the DSA , Evaluate the accuracy of the 16-slice CTA in the diagnosis of aneurysms .Results:59 aneurysms were detected by DSA , 56 aneurysms were detec-ted by CTA, the sensitivity, specificity and accuracy were 94.6%, 100%, 95 respectively.Conclusion:16-slice CTA and DSA can be obtained similar results, it has higher sensitivity and specificity , fast, non-invasive, it can replace DSA screening and preoperative eval-uation of intracranial aneurysms .
