目的 探讨多层螺旋CT血管造影 三维重建技术应用于脑血管病变中的诊断 效果，为脑血管病变的诊治提供客观的依 据。方法 采用回顾性的方法，选取在我 院2015年3月-2016年2月收治的住院脑血 管病变患者临床资料85例作为研究对象， 应用多层螺旋CT血管造影进行相关检查， 并在工作站进行三维重建，分析脑血管病 变患者的解剖关系。结果 85例脑血管病 变患者中有29例动脉瘤患者，25例动静脉 畸形患者，11例脑血管狭窄患者，20例胚 胎性大脑后脉瘤(先天性发育异常)患者； 35例脑血管病变患者的多层螺旋CT血管造 影均显示清晰，能够观察到动脉瘤的具体 位置的大小形态；经过影像学检查之后不 难发现85例脑血管病变患者中阳性例数 为81例，阳性率为95.29%(假阳性例数为4 例，假阳性率为4.71%)。结论 多层螺旋 CT血管造影三维重建技术应用于脑血管病 变中的诊断率较高，能够对脑血管病变进 行确诊，错误率极低。

Objective Scientific research of multislice spiral CT angiography 3D reconstruction technology application in the diagnosis of cerebral vascular diseases, for the treatment of patients with cerebral vascular disease to provide scientific reference data. Methods Using retrospective method, selected in our hospital from August 2015 - 2016 February were cerebral vascular lesions in patients with clinical data of 35 cases as the research object, the application of multislice spiral CT angiography for examination, using spss20.0 statistical software for statistical analysis after the application of multi-slice spiral CT angiography in workstation for 3D reconstruction and analysis of the anatomical relationship of patients with vascular lesions of the brain. Results 35 cases of patients with cerebral vascular disease in 19 patients with aneurysm patients, 10 cases of dynamic venous malformation patients, 2 cases of cerebral vascular stenosis in patients with, 4 cases of embryonic brain aneurysm (congenital dysplasia) patients, each set of data comparisons were statistically significant (P<0.05), 35 cases of patients with cerebral vascular disease of multislice spiral CT angiography showed clear, to observe the size and shape of the specific location of the aneurysm, after pathological examination is not difficult to find 31 of 35 cases of patients with cerebral vascular disease in positive cases, positive rate was 88.57%. Conclusion Multi-slice spiral CT angiography (made image three-dimensional reconstruction techniques used in The diagnostic effect of cerebral vascular disease is more significant.
