基底动脉成窗变异的MRA诊断及其临床意义

MRA Diagnosis of Fenestration of the Basilar Artery and its Clinical Significance

目的:探讨基底动脉成窗变异的MR血管成像(MRA)表现及其临床意义。材料与方法:回顾分析98例MRA的图像资料,分析各类资料中基底动脉成窗变异的检出率及影像表现特征。结果:MRA发现基底动脉成窗变异11例。MRA发现的11例中5例为裂隙型,6例为凸透镜型。结论:MRA对基底动脉成窗变异的诊断有重要价值。

Purpose： To study MRA features and its clinical value of fenestration of the arterior communicating artery.Materials and Methods： The data of MRA in 98 cases.Results： Basilar artery fenestration was found in 11 cases,five of them were small with slit-pattern,six were large with convex-lens-pattern.Conclusion： MRA is a very effective method for the diagnosis of Basilar artery fenestration.
