摘要:
目的:通过兔视神经大体解剖与磁共振影像的对比,探讨兔视神经磁共振成像效果,为视神经病变的磁共振诊断提供实验依据。方法:采用3.0 T磁共振仪对12只正常兔视神经进行高分辨磁共振扫描和Mn2+增强扫描,并与兔视神经大体解剖进行对照分析,观察视神经的扫描效果。结果:兔视神经自眼球后极部发出后呈水平方向走行,双侧视神经眶内段夹角约为135.5°,在接近颅脑中轴线部位双侧视神经并行后形成视交叉。高分辨磁共振能够清晰显示兔视神经各段的解剖结构,Mn2+增强能够全程显示视神经走行、视交叉、外侧膝状体及上丘结构。结论:磁共振能够清晰显示兔眼视神经的走形及解剖结构,与大体解剖具有良好的一致性。
Abstract:
Aim: To observe the feasibility of MRI of rabbit optic nerve by comparing with the gross anatomy. Methods: Twelve rabbit optic nerves underwent high resolution scan and manganese enhanced scan by MRI with 3.0 Tesla system. The results of MRI were compared with the gross anatomy of rabbit optic nerve. Results: The optic nerve of rabbit emerged from the posterior surface of the global, traveled horizontally in intraorbital segment with the angle 135.5° between bilateral optic nerves, paralleled in intracranial segment, and formed the optic chiasma. MRI with highresolution could display the anatomical structures of rabbit optic nerve. Mn2+ enhanced scan could clearly reveal the optic nerve, optic chiasma, lateral geniculate body and superior colliculus. Conclusion: MRI with highresolution well displays the shape of rabbit optic nerve, which fits with the gross anatomy.
