高分辨率磁共振血管成像对脑血管分级的探讨

Discussion about Branches of Intracranial with High Spatial Resolution MRA

本文通过对１０７例脑血管ＭＲＡ资料的回顾性分析。着重探讨高分辨率ＭＲ用３Ｄ－ＴＯＦ－ＴＯＮＥ法对脑血管分支的显示程度，结果表明，高分辨率ＭＲ用３Ｄ－ＴＯＦ－ＴＯＮＥ法能清楚地显示出脑动脉的末梢小血管分支。

In this paper,107 cases were retrospected to evaluate the value of MRA in cerebral artery.All cases imaged with 3D TOF TONE technique.As a result,High spatial resolution with 3D TOF TONE technique was most helpful invisulization of small vessel branches of intracranial artrey.
