| 摘 要： | 目的:探讨64层CT血管造影在自发性蛛网膜下腔出血的病因诊断中的价值。方法:对2009年1～12月97位患有自发性蛛网膜下腔出血的病人行64层CT血管造影成像扫描,应用容积再现、最大密度投影、曲面重建、多平面重建等后处理技术显示血管,以明确病因。结果:64层CTA诊断12例正常,1例颈内动脉海绵窦瘘、9例动静脉畸形,75例动脉瘤,所有病例与数字减影血管造影和/或手术对比证实,其中12例正常病例行DSA检查,64层CTA漏诊1例,但其总的敏感性为98.7%,特异性为100%。结论:64层CT血管造影对自发性蛛网膜下腔出血的病因诊断准确性高,且简单、快速、微创、安全和经济,可作为自发性蛛网膜下腔出血病因诊断的首选检查方法。

| Abstract: | Objective：To investigate the value of CT angiography（CTA） in the etiological diagnosis of spontaneous subarachnoid hemorrhage（SAH） with 64-slice CT.Methods：from January to December 2009,97 patients with spontaneous subarachnoid hemorrhage underwent CTA with 64-slice CT,post-processing techniques such as volume rendering（VR）,maximum intensity projection（MIP）,curved planar reformation（CPR）,multiplanar reformation（MPR） were used to show blood vessels with a clear cause.Results：CTA diagnosis of 12 cases of normal,one case of carotid cavernous fistula,nine cases of arterioven-ous malformation,75 cases of aneurysm,all patients were confirmed with digital subtraction angiography（DSA） and or surgery,12 normal cases diagnosed by DSA,64-slice CTA missed one case,but the overall sensitivity of 98.7 % and specificity of 100%.Conclusion：64 slice CT angiography is a simple,rapid,minim-ally invasive,safe and economical method in the diagnosis of the cause of spontaneous subarachn-oid hemorrhage with a high accuracy,it can be used as a preferred method in the early etiological diagnosis of spontaneous subarachnoid hemorrhage. |
