兔坐骨神经扩散张量纤维束示踪

Diffusion Tensor Tractography of Rabbit Sciatic Nerve

目的:探讨DTI成像能否用于显示兔的坐骨神经。方法:三只成年家兔,运用3T磁共振扫描仪、8通道相控阵膝关节线圈和DTI成像方法扫描兔股部,后处理3D显示坐骨神经的走行。结果:运用DTI3D纤维束成像显示了兔的坐骨神经,其路径与兔坐骨神经大体解剖部位一致。结论:DTI成像在动物周围神经的研究中有一定的应用前景。

Objective：To investigate whether MR diffusion tensor imaging with fiber tracking could be performed for rabbit sciatic nerves. Methods： In 3 healthy New Zealand albino rabbits,the proximal thigh was performed DTI examination on 3.0Tesla MR scanner with 8-channel phased array knee coil. Tractography software package was used for visualizing the sciatic nerve. Results：The sciatic nerve could be detected by DTI with fiber tracking,and the path is accordant with the gross anatomy of rabbit sciatic nerve. Conclusion：Diffusion tensor imaging is prospective for studying peripheral nerves.
