目的 探讨磁共振成像(MRI)的 3D-T1-SPACE 序列扫描在脑血管斑块狭窄 及栓塞诊断中的应用价值。方法 回顾性 分析了20例行MRI 3D-T1-SPACE、MRA、 颅内血管MRI高分辨检查的MRI资料。结果 基底动脉斑块9例、右侧大脑中动脉斑块6 例、左侧大脑中动脉斑块5例。MRI尤其用 3D-T1-SPACE序列扫描可以从各个不同的 角度观察靶血管走形及管腔情况，尤其对 管腔的狭窄特别敏感。结论 MRI 3D-T1- SPACE 序列可从各个角度清晰的显示脑血 管斑块的解剖结构，是诊断脑血管狭窄及 栓塞的主要方法，也为临床提供了更多信 息，值得临床推广。

Objective To investigate the value of 3D T1 SPACE sequence in stenosis and thrombosis cerebrovascular plaques. Methods The retrospective analysis of the 20 routine MRI 3D-T1- SPACE, MRA, intracranial vascular high-resolution MRI examination of MRI data. Results Basal artery plaque in 9 cases, 6 cases of right middle cerebral artery plaque, the left middle cerebral artery plaque in 5 cases. MRI especially in 3DT1-SPACE scanning sequence can be observed from the Angle of the different target vascular lumen and contorts, especially particularly sensitive to the lumen of stenosis. Conclusion MRI 3D-T1-SPACE sequence can be clear display from various angles and cerebrovascular anatomy structure of plaque, is the main method in the diagnosis of cerebrovascular stenosis and thrombosis, also provide more information for clinical, worth clinical promotion
