| 摘 要： | 目的：研究脑动静脉畸形（ＡＶＭ）的ＭＲＩ特征，探讨其诊断价值。方法：使用ＧＥｓｉｇｎａ ｅｃｈｏ ｓｐｅｅｄ１．５Ｔ超导ＭＲ机对７１例ＡＶＭ患者分别行ＭＲＩ及ＭＲＡ检查。ＭＲＩ采用ＳＥＴ１和ＦＳＥＴ２加权序列，ＭＲＡ采用３Ｄ－ＴＯＦ序列。结果：ＭＲＩ及ＭＲＡ能显示ＡＶＭ的瘤巢，ＡＶＭ的继发改变ＭＲＩ能很好显示，ＭＲＡ能显示ＡＶＭ的三维解剖结果。结论：ＭＲＡ和ＭＲＩ是无创性评从脑ＡＶＭ的有效方法，两

| Abstract: | Objective:To evaluate MRI and MRA in diagnosis of intracranial AVM.Methods:71 cases of AVM were studied retro- spectively with MRI and MRA on a GE signa echo speed 1.5T scanner. MRI was performed with SE T1 and FSE T2 weighted sequences, and MRA was done with 3D-TOF sequences. Resuhs: The nets of AVM can be seen on both MRI and MRA.The secondazy changes of AVM were well defined on MRI and the three dimensional anatomy of AVM could be demonstrated cleary on MIiA. Condusion: MRA and MRI have great value in noninvasive evaluation of intracranial AVM. Moreover, MRA coupled with MRI may improve the diagnostic accura- cy. |
