目的：应用MRI成像技术显示正常人眼球运动神经的颅内段、眶内段及海绵窦段的影像学征象。方法以28例正常人为研究对象，年龄25～39岁，平均年龄32岁，均于3.0T MR扫描仪上行MRI检查，扫描平面除常规的平面扫描，还包括特定的斜平面扫描，眼球运动神经脑池段采用头线圈，3D-COSMIC序列扫面，层厚0.8 mm；海绵窦段采用头线圈，层厚2.0 mm，FSE T1WI扫描；眼眶段则采用表面线圈，层厚2.0 mm，FSE T1WI扫描，运用多层面重建技术分别在沿神经长轴的层面显示3对眼球运动神经的走行及毗邻关系，观察各对眼运动神经的MRI影像特征。结果脑池段的动眼神经与展神经显示率为28/28（100%），滑车神经显示率为27/28（96.4%）；海绵窦段的动眼神经显示率为28/28（100%），展神经及滑车神经显示率为20/28（71.4%）；眶内段动眼神经显示率为27/28（96.4%），展神经显示率为25/28（89.2%），滑车神经显示率为13/28（46.4%）。结论 MRI能够清晰地显示眼球运动神经及其毗邻关系，是神经影像学的首选检查方法。

Objective Application of MRI imaging shows the oculomotor nerve of normal intracranial segment of intraorbital cavernous sinus and radiographic signs. Methods Chose 28 normal persons as the object of study, age 25~39 year old, average 32 years old, were in the 3.0T MR scanner MRI examination, scanning plane except plane scanning routine, including oblique plane speciifc scanning, the cisternal segment of the oculomotor nerve head coil, 3D-COSMIC sequence scanning, layer thickness 0.8 mm the cavernous segment;the head coil, slice thickness 2.0 mm, FSE T1WI scan;orbital section adopts the surface coil, slice thickness 2.0 mm, FSE T1WI scan, using multiplanar reconstruction technique showed three of oculomotor nerve distribution and adjacent relations along nerve axis level, MRI imaging features were observed in each ocular motor nerve the. Results The oculomotor and abducens nerve cisternal segment of the display rate of 28/28 (100%), the trochlear nerve display rate of 27/28 (96.4%);the cavernous segment of the oculomotor nerve display rate of 28/28 (100%), abducent nerve and the trochlear nerve display rate of 20/28 (71.4%);intraorbital segment of the oculomotor nerve display rate of 27/28 (96.4%), abducent nerve display 25/28 (89.2%), 13/28 (46.4%) the trochlear nerve. Conclusion MRI can clearly show the oculomotor nerve and its adjacent relations, is the preferred neuroimaging methods.
