摘要
目的：分析脑ＡＶＭ３Ｄ－ＴＯＦ及３Ｄ－ＰＣ法ＭＲＡ表现，探讨其诊断意义。材料和方法：使用美国ＧＥＳｉｇｎａ１．５ＴＭＲ超导扫描仪对１４例患者分别行ＳＥ序列，３Ｄ－ＴＯＦ及３Ｄ－ＰＣＭＲＡ检查。结果：１４例患者ＡＶＭ位于颞顶叶２例，顶叶２例，颞枕叶２例，顶枕叶１例，枕叶３例，额叶３例，脑干１例；供血动脉来自大脑中Ａ５例，大脑前Ａ３例，大脑后Ａ１例，联合供血５例；引流Ｖ中６例引流入大脑深Ｖ，２例引流入乙状窦。结论：ＭＲＡ能准确显示畸形血管团及异常供血Ａ、引流Ｖ，结合ＭＲＩ可大大提高其诊断准确率，为临床筛选及术后随诊的首选方法。
Purpose:To analyze the MRA features of cerebral AVM with 3D-TOF、3D-PC methods and discuss its diagnostic significance.Materials and Methods:14 cases were carried out with SE sequence,3D-TOF and 3D-PC MRA on a 1.5T MR canner.Results:The located of foci included temporal-parietal lobe(2),parital lobe(2),temporal-occipital lobe(2),parietal-occipital lobe(1),occipital(3),frontal lobe(3)and brain stem(1).The feeding arteries of the nidi were derived from cerebral middle artery(5 cases)、cerebral anterior artery(3 Cases)、cerebral posteror atrery(1 Cases)and mixed(5 Cases).Veins of the foci included 14 cases drained to different sites of saggital sinus(6),cerebral surface of cerebrum(3),deep cerebral veins(3) and sigmoid sinus(2).Conclusion:MRA could clearly demonstrate the nidi,feeding arteries and draining veins of AVM.Diagnostic accuracy of MRA could be improved markedly by combining MRI with 3D-TOF and PC.MRA could be used as first choice for clinical screening and post-operative follow-up.
