Abstract：
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.
摘要：
应使用标准化的指南和评分系统进行周围神经病变的MR成像诊断。基于MR成像的神经病变评分报告和数据系统（NS-RADS）是一种新设计的分类系统（在AJR中已出版），可用于根据临床病史和检查结果传达周围神经病变的类型和严重程度。该系统涵盖的神经病变和周围神经疾病的范围包括神经损伤，诱捕,肿瘤，弥漫性神经病,和介入后状态。该分类系统还描述了局部肌肉神经支配变化的时间MR成像外观。这篇综述文章基于预先发表在美国Roentgenology杂志上的多中心验证研究，讨论了用于周围神经评估的最佳MR成像的技术考虑因素，并讨论了NS-RADS分类及其严重程度量表，并说明了每种分类下的条件。读者可以获得NS-RADS分类系统的知识，并学会将其应用于他们的实践中，以改善跨学科沟通和及时的患者管理。
