Abstract： 目的探讨面肌痉挛及三叉神经痛的神经与周围血管显示的最佳MR扫描序列. 方法对40例面肌痉挛及三叉神经痛病人的脑池段面神经和三叉神经用三维时间飞跃-扰相梯度回波(3D TOF-SPGR)和三维快速高级自旋回波(3D FASE)2种扫描序列进行扫描,并对其与周围血管的关系显示进行分析.结果 38例经手术证实,3D TOF-SPGR序列图像显示其中33例面神经和三叉神经单侧存在邻近血管压迫或接触,5例无接触,3D FASE序列图像显示其中26例面神经和三叉神经单侧存在邻近血管压迫或接触,12例无接触.统计学分析结果表明2种扫描序列显示面神经和三叉神经对邻近血管的压迫或接触差异有显著性意义(χ2=5.14,P=0.016).结论就显示神经与邻近血管的关系而言,3D TOF-SPGR序列明显优于3D FASE序列,是临床上面肌痉挛和三叉神经痛病人行MR检查首选的扫描序列.
