弥散张量成像在周围神经损伤中的应用进展

弥散张量成像是基于水分子的弥散运动获取不同组织各向异性信息的一种磁共振成像技术,在周围神经损伤修复、微病变识别和神经肿瘤等方面中发挥重要作用。弥散张量成像在周围神经损伤中临床应用尚不广泛,测量参数受技术设置和序列规范等多种因素的影响,测定方案的标准化和不同功能参数的定量仍有待进一步研究。

Advance in Diffusion Tensor Imaging for Peripheral Nerve Injury (review)

Diffusion tensor imaging is a magnetic resonance imaging technology, based on the diffusion motion of water molecules, to obtain anisotropy informations of different tissues, which is used for early identification, accurate localization and grading in various fields of peripheral nerve injury, such as peripheral nerve injury repair, micro-lesion recognition and neuro-tumor. However, since diffusion tensor imaging is still at the early stage of clinical research, and the measurements are influenced by various factors such as technical settings and sequence specifications, the standardization of clinical measurement protocols and the quantification of parameters remain to be further studied.
