Recent advances in the technology of magnetic resonance (MR) imaging (MRI) have made the diagnostic evaluations for peripheral nerve disorders shift from the clinical and physiological examination to the anatomical study. As a sensitive noninvasive tool, MR neurography could directly display high-resolution longitudinal and cross-sectional images of peripheral nerves, including nerve compression, nerve inflammation, nerve trauma, nerve recovery, and systemic neuropathies, thereby the morphology of intraneural and extraneural lesions can be visualized. Thus neurologists, as well as specialist radiologists, should be highly familiar with the various new types of image findings in this steadily advancing field. The purpose of this review is to overview how to evaluate peripheral nerve problems with MR neurography and its current limitations and advances in experimental MR research. The techniques for peripheral nerve MR neurography will also be discussed.
磁共振（MR）成像技术的最新进展使得外周神经疾病的诊断评估从临床和生理学检查转向解剖学研究。作为一种敏感的无创工具，MR 神经成像可以直接显示外周神经的高分辨率纵向和横截面图像，包括神经压迫、神经炎症、神经创伤、神经恢复和系统性神经病变，从而可以观察到神经内和神经外病变的形态。因此，神经科医生和专业放射科医生都应该非常熟悉这个不断发展的领域中的各种新型图像发现。本综述的目的是概述如何使用 MR 神经成像评估外周神经问题及其在实验性 MR 研究中的当前局限性和进展。还将讨论外周神经 MR 神经成像的技术。
