摘　　要：目的:探究脑动脉粥样硬化筛查中采用时间飞跃法(MRA)的临床应用价值。材料与方法:回顾分析我院2013年1月至2015年8月间临床似诊脑动脉粥样硬化患者129例,所有患者均进行时间飞跃法(3D-TOF)MRA检查,扫描完成后分别采用多平面的重建(MPVR)、容积重建(VR)、最大强度投影(MIP)以及表面重建(SSD)等方法进行重建图像进行分析。结果:经3D-TOF法MRA检查,129例患者中脑动脉血管显示结构较为清晰,采用以MPVR、VR以及MIP等重建方式观察,发现其中53例患者出现血管狭窄及闭塞。结论:在检查脑动脉粥样硬化时,TOF-MRA简便、无创,联合三维处理技术可作为筛查脑动脉粥样硬化的重要手段。Purpose： To explore cerebral atherosclerosis screening by using time leap（ MRA） in the clinical application value. Materials and Methods： Retrospective analysis from January 2013 to August 2015 between the clinical diagnosis of 129 cases of patients with cerebral atherosclerosis,all patients were time leap method（ 3 D TOF） MRA examination,after the scan is complete,it adopts multiple planar reconstruction（ MPVR）,volume reconstruction（ VR）,maximum intensity projection（ MIP） and surface reconstruction（ SSD） method for image reconstruction were analyzed. Results： By the method of 3 d-TOF MRA examination,129 cases of patients with middle cerebral artery blood vessels display structure is relatively clear,use with MPVR,VR and MIP reconstruction methods such as observation,found in 53 patients with vascular stenosis and occlusion. Conclusion： Cerebral atherosclerosis in check,TOF MRA-simple,noninvasive,joint 3 d processing technology can be used as an important means of screening for cerebral atherosclerosis.
