摘　　要：目的探讨64排螺旋CT血管造影（CTA）对颅内动脉瘤早期诊断的临床意义。方法选取疑似颅内动脉瘤的蛛网膜下腔出血患者42例，在病情允许条件下首先进行64排螺旋CTA检查，随后进行DSA检查，采用自身配对四格表卡方检验，分析CTA与DSA检查结果的差异性。结果39例患者经CTA检查证实为颅内动脉瘤（瘤体直径2～26mm），1例患者CTA检查疑似动脉瘤，1例患者CTA检查阴性。41例患者经DSA检查发现动脉瘤，1例患者DSA检查阴性。CTA与DSA动脉瘤检出率比较差异无统计学意义（χ^2=0．263，P=0．608）。结论CTA对于直径不小于2mm动脉瘤的早期诊断较准确。Objective To assess the clinical value of CT angiography （CTA） in early diagnosis of intracranial aneurysms. Methods Forty-two patients with subarachnoid hemorrhage suspected to arise from intracranial aneurysms underwent 64-slice spiral CTA followed by digital subtraction angiography （DSA）. Chi-square test was employed to analyze the differences between the results by CTA and DSA. Results CTA confirmed the diagnosis of intracranial aneurysms （2-26 in diameter） in 39 patients, with suspected aneurysm in 1 patient and negative result in another. DSA identified intracranial aneurysms in 41 patients and showed negative result in 1 patient. The aneurysm detection rate showed no significant difference between CTA and DSA （χ^2=0.263,P=0.608）. Conclusion CTA can accurately diagnose aneurysm with diameter no less than 2 mm.
