橄榄桥脑小脑萎缩脑后循环改变的MRI分析

The analysis of MRI after the changes of brain retral cycle in olivopontocerebellar atrophy

目的:利用3.0TMRI的血管成像技术探讨橄榄桥脑小脑萎缩发病与其血供之间的相互关系。方法:分别观察了50例健康人和31例橄榄桥脑小脑萎缩患者椎—基底动脉的管径、血管走形、狭窄、闭塞和缺如发生情况并进行统计学分析。结果:患者组的血管异常发生率显著高于对照组。结论:椎—基底动脉血管形态、走形异常与橄榄桥脑小脑萎缩发病存在密切关系,可以为橄榄桥脑小脑萎缩的早期诊断提供参考依据。

Objective:To explore the relationship between the olivop ontocerebellar atrophy and its blood supply by using vascular imaging of 3.0T MRI.Methods:The incidences of vertebrobasilar artery diameter,blood vessels course,stenosis,occlusion and absence form of 50 healthy people and 31 patients with olivopontocerebellar atrophy were observed,respectively and statistical analysis was done.Results:The incidences of vascular abnormalities of patients were significantly higher than those in control group.Conclusion:There is a close relationship among vertebral basilar artery vascular morphology,abnormal shape and olivopontocerebellar atrophy disease.It can provide evidences for early diagnosis of olivoponcerebellar atrophy.
