摘要
目的应用3D-CISS(3-D Constructive Interference in Steady State)序列对脑池段眼运动神经的异常毗邻组织结构进行显示与研究,为临床诊断及手术获得详尽的MR影像资料。方法对23名眼运动障碍患者进行3D-CISS序列MR成像,应用MPR技术在最佳方位层面观察眼运动神经与其异常毗邻组织的压迫关系。结果 23例单侧眼运动障碍患者的3D-CISS序列MR成像均显示相应眼运动神经明显受压变形:动眼神经受压11例,其中大脑后动脉(PCA)血管压迫5例,小脑上动脉(SCA)压迫1例,基底动脉(BA)压迫2例,肿瘤压迫3例;展神经受压10例,其中基底动脉(BA)血管压迫4例,小脑前下动脉(AICA)压迫2例,肿瘤压迫4例;滑车神经受压2例,均为小脑上动脉(SCA)分支血管压迫。结论 3D-CISS序列结合MPR技术能够准确显示眼运动神经的毗邻关系,具有重要的临床意义。
Objective To obtain the detailed anatomical data of image for clinic through the application of 3D-CISS sequence in displaying the cisternal segment of the ophthalmic motion nerves and its abnormal adjacent relationships. Methods 23 patients with palsy of the ophthalmic motion nerves underwent 3D-CISS MR imaging, the syntopy of the ophthalmic motion nerves to its related pathological changes were observed from the different angles on multi-planar reconstruction （MPR） images. Results 23 patients with palsy of the unilateral ophthalmic motion nerves were all displayed with the corresponding apparent distortion caused by press： 11 oculomotor nerves were pressed, among them 5, were pressed by PCA, 1 by SCA, 2 by BA, 3 by tumor in the pontine cistern; 10 abducent nerves were pressed, among them 4 were pressed by BA, 2 by AICA and 4 by tumor in the pontine cistern; 2 trochlear nerves were all pressed by the branch of SCA. Conclusion 3D-CISS sequence and MPR technique are the optimal imaging methods for the display of the syntopy of the ophthalmic motion nerve to its related organization.
