我们检查了是否可以对坐骨神经进行带有纤维追踪的磁共振扩散张量成像。使用带有 2 通道相控阵线圈的 1.5 特斯拉 MR 扫描仪对 3 名健康志愿者的大腿近端进行了检查。虽然坐骨神经本质上容易受到运动、场不均匀性和扩散成像技术的快速 T-2 松弛的影响，但可以在所有 3 名受试者中检测到坐骨神经并与 T-2 加权图像相关联。需要进行进一步的研究以提高信噪比，并看看是否可以检测到比坐骨神经更小的周围神经。 (C) 2004 Elsevier Inc. 保留所有权利。
We examined if MR diffusion tensor imaging with fiber tracking could be performed on the sciatic nerve. In 3 healthy volunteers the proximal thigh was examined on a 1.5-Tesla MR-scanner with a 2-channel phased-array coil. Though inherently susceptible to motion, field inhomogeneities, and fast T-2-relaxation of the diffusion imaging technique, the sciatic nerve could be detected and correlated to T-2-weighted images in all 3 subjects. Further investigations need to be done to improve the signal-to-noise ratio and to see if smaller peripheral nerves than the sciatic nerve can be detected. (C) 2004 Elsevier Inc. All rights reserved.
