64层螺旋CT血管成像在自发性蛛网膜下腔出血中的应用价值

Application value of 64 slice spiral CT angiography in spontaneous subarachnoid hemorrhage

目的:总结、探讨64层螺旋CT血管成像在自发性蛛网膜下腔出血诊断中的应用价值。方法:收治自发性蛛网膜下腔出血患者110例,给予64层螺旋CT扫描及数字减影血管造影,再以容积再现、曲面重组、最大密度投影、多平面重组等方法处理。结果:110例ASH患者均经过DSA、手术证实。动脉瘤及脑血管畸形105例,检出率95.45%,CTA诊断符合率达100.00%。结论:64层螺旋CT血管成像在自发性蛛网膜下腔出血诊断中应用价值极高,可为临床疾病诊断、治疗提供有效依据。

Objective:To summarize and discuss the value of 64 slice spiral CT angiography in the diagnosis of spontaneous subarachnoid hemorrhage.Methods:110 patients with spontaneous subarachnoid hemorrhage were selected.64 slice spiral CT scanning and digital subtraction angiography were given,and then the volume rendering,surface reconstruction,maximum density projection,multi planar reconstruction and other methods were given.Results:110 cases of ASH were confirmed by DSA and operation.aneurysm and cerebral vascular malformation were 105 cases,the detection rate was 95.45% ,and the rate of CTA diagnosis was 100%.Conclusion:64 slice spiral CT angiography in the diagnosis of spontaneous subarachnoid hemorrhage is very high value.It can provide an effective basis for clinical diagnosis and treatment.
