| 摘 要： | 目的通过大样本病例研究颅内动脉开窗畸形磁共振血管造影(MRA)的检出率、好发部位及其临床意义。方法2009年10月至2011年3月行MRA 2 036例患者,确诊动脉开窗畸形25例(开窗畸形组),其中男性14例,女性11例;年龄30~81岁,平均年龄60.5岁。全部行头颅三维时间飞跃MRA(3D-TOF MRA)扫描,将原始图像经工作站处理,得到最大密度投影(MIP)和容积重组(VR)图像,分析颅内动脉开窗畸形的影像学特点,与伴发动脉瘤之间的相关性。结果 2 036例患者中,发现动脉开窗畸形共计25例(检出率1.23%,25/2 036),其中位于基底动脉11例;位于椎动脉颅内段4例;位于前交通动脉区6例;位于大脑中动脉3例;位于大脑后动脉1例。25例开窗畸形中有6例合并动脉瘤,4例位于颈内动脉颅内段,2例位于大脑前动脉。结论 3D-TOF MRA检查能准确诊断、显示颅内动脉开窗畸形。
