1、64排螺旋CT血管造影对脑动静脉畸形的诊断价值王兵杨景明李云张家口宣化区医院放射科摘要:目的探讨64排螺旋CT血管造影(CTA)在脑动静脉畸形(AVM)诊断屮的价值。方法回顾15例经手术或DSA证实的AVM患者,术前15例患者均行64排螺旋CT血管造影。均采用GE64排LightspeedVCT获得原始图像,然后在工作站中进行多层面重建(multiplanarreconstruction,MPR)、容积再现(volumerendering,VR)、薄层块最大密度投影(thin-slabmaximumintensityprojectjon,TSMIP)。结果
2、15例AVM患者的CTA断面和重建图像均显示大小不等的畸形血管团。13例发现供血动脉(86.7%),2例未见显示,15例均见明确的引流静脉或扩大的静脉窦(100%),单支动脉供血11例,其中大脑前动脉2例,大脑中动脉5例,大脑后动脉3例,后交通动脉1例,多支动脉供血2例。引流静脉汇入上矢状窦6例,直窦、乙状窦分别3例,上矢状窦和乙状窦1例,窦汇1例,上矢状窦、横窦和岩上窦1例。其中1例合并动脉瘤。结论64排螺旋CTA在脑动静脉畸形(AVM)诊断中有十分重要的价值,为临床治疗方案的制定及术后随访提供依据,可作为脑动静脉畸形(AVM)的术前主要检查方法。关键词
