A standardized guideline and scoring system should be used for the MR imaging diagnosis of peripheral neuropathy. The MR imaging-based Neuropathy Score Reporting and Data System (NS-RADS) is a newly devised classification system (in press in AJR) that can be used to communicate both type and severity of peripheral neuropathy in the light of clinical history and examination findings. The spectrum of neuropathic conditions and peripheral nerve disorders covered in this system includes nerve injury, entrapment, neoplasm, diffuse neuropathy, and post-interventional states. This classification system also describes the temporal MR imaging appearances of regional muscle denervation changes. This review article is based on the multicenter validation study pre-published in American journal of Roentgenology and discusses technical considerations of optimal MR imaging for peripheral nerve evaluation and discusses the NS-RADS classification and its severity scales with illustration of conditions that fall under each classification. The readers can gain knowledge of the NS-RADS classification system and learn to apply it in their practices for improved inter-disciplinary communications and timely patient management.
应当使用标准化的指南和评分系统对周围神经病进行磁共振成像诊断。基于磁共振成像的神经病评分报告和数据系统（NS-RADS）是一种新设计的分类系统（即将在 AJR 发表），可根据临床病史和检查结果，用于交流周围神经病的类型和严重程度。该系统涵盖的神经病变和周围神经疾病谱包括神经损伤、嵌压、肿瘤、弥漫性神经病和介入后状态。该分类系统还描述了区域性肌肉失神经支配改变的时间性磁共振成像表现。本文基于多中心验证研究，该研究先前发表于《美国放射学杂志》，讨论了用于周围神经评估的最佳磁共振成像技术的注意事项，并讨论了 NS-RADS 分类及其严重程度分级，并举例说明了每种分类下的病变情况。读者可以了解 NS-RADS 分类系统，并学习在实践中应用该系统，以改善跨学科交流和及时的患者管理。
