Neuropathy Score Reporting and Data System (NS‐RADS): A Practical Review of MRI-Based Peripheral Neuropathy Assessment

Abstract

The Neuropathy Score Reporting and Data System (NS-RADS) is a newly developed MR imaging-based classification that standardizes reporting and multidisciplinary communication of the MR imaging diagnosis and follow-up of peripheral neuropathies. NS-RADS classification has shown to be accurate and reliable across different centers, readers' experience levels, and degrees of peripheral neuropathies, which include nerve injury, entrapment, neoplasm, diffuse neuropathy, post-interventional status, and temporal changes in muscle denervation. This article brings a practical review of NS-RADS classification, representative MR cases, and a step-by-step tutorial on how to approach this staging system. The readers can gain knowledge and apply it in their institutions, aiming to standardize the communications between specialties and improve patient management.
