摘要 ①目的探讨脑发育性静脉异常的MRI表现,评价各成像序列的诊断价值。②方法23例脑发育性静脉异常均行MRI平扫和增强检查,其中9例行磁敏感加权成像。③结果23例脑发育性静脉异常发生于额叶白质12例,顶叶白质5例,颞叶2例,小脑半球4例;合并出血1例,位于幕下;并发海绵状血管瘤1例。MR平扫显示病灶11例,其中表现为条状流空信号者7例,表现为T2WI放射状高信号者4例;MR增强检查显示所有病灶,表现为"海蛇头"样强化特征。9例行SWI者均能清晰显示病灶,表现为"海蛇头"样低信号影。④结论脑发育性静脉异常多发生于幕上额顶叶白质及小脑半球,合并出血少见,可并发海绵状血管瘤。MR平扫难以显示细小病灶,MR增强检查是显示脑发育性静脉异常的有效方法,SWI对小静脉病变较敏感,能取代MR增强检查用于发育性静脉异常的诊断。
