磁共振神经成像在周围神经疾病的临床应用(英文)

磁共振成像技术的进展已经使周围神经疾病的诊断从传统的临床和电生理检查向解剖学研究转化。磁共振神经成像能够获取周围神经纵切面和横切面的影像,来直接观察神经内外的病灶。磁共振神经成像作为一种敏感的非侵入性技术,可用于诊断周围神经的神经压迫症、炎症、创伤、康复和系统性神经疾病。这就要求神经科医生与放射科医生一样,也要熟识该领域各种新技术的影像表现。本文将对磁共振神经成像在周围神经疾病的临床应用以及目前存在的问题和磁共振实验研究作一综述,包括相应的技术介绍。

Clinical application of magnetic resonance neurography in peripheral nerve disorders

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 sys- temic 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 neurogra- phy and its current limitations and advances in experimental MR research. The techniques for peripheral nerve MR neurography will also be discussed.
