【摘要】目的 探讨64排螺旋CT血管成像(CTA)对自发性蛛网膜下腔出血病因的诊断价值.方法 对256例疑自发性蛛网膜下腔出血的患者行64排CTA检查,得到的图像应用Philips高级血管分析(AVA)软件,采用容积再现(VR),多平面重建(MPR)和最大密度投影(MIP)等技术对图像进行处理.其中21例同时行磁共振血管造影(MRA)检查,92例同时行数字减影血管造影(DSA)检查.结果 256例中,重度血管硬化狭窄94例,动脉瘤123例,大致正常35例,19例进行了动脉瘤栓塞手术,102例进行了外科手术,其中91例动脉瘤进行了外科夹闭手术,9例进行了开颅血肿清除术,2例进行了畸形血管切除手术.结论 64排CTA能清晰地显示出脑血管的三维信息,发现动脉瘤、动静脉畸形、血管狭窄等,可以清晰地显示出动脉瘤的瘤颈、大小、部位、形态及供血动脉的解剖关系.%Objective To investigate the value of 64-siicc spiral CT angiography(CTA) in the diagnosis of spontaneous subarachnoid hcmorrhagc(SAH). Methods CTA was performed in 256 patients with the suspected SAH . The original images were studied by Philips advanced vascular analysis ( AVA ) software ,and the VR , MIP ,MPR techniques were used to reconstruct the images. Among them , 21 cases performed magnetic resonance angiography ( MRA ) , 92 cases performed digital subtraction
