Neuropathy Score Reporting and Data System: A Reporting Guideline for MRI of Peripheral Neuropathy With a Multicenter...

Area of Science:

• Radiology
• Neurology
• Medical Imaging

Background:

• Standardized guidelines and scoring systems are needed for peripheral neuropathy (PN) evaluation and MRI reporting.
• Current methods lack consistency, hindering accurate diagnosis and communication.

Purpose of the Study:

• To develop and validate the Neuropathy Score Reporting and Data System (NS-RADS) for classifying and grading PN on MRI.
• To establish a reliable system for consistent reporting of nerve pathologies.

Main Methods:

• Retrospective analysis of 100 patients with nerve imaging and clinical diagnoses.
• Development of NS-RADS with defined criteria for PN classification (unremarkable, injury, neoplasia, entrapment, diffuse, NOS, postintervention).
• Validation by 11 radiologists with varying experience, blinded to clinical diagnoses, assessing interobserver agreement and accuracy.

Main Results:

• NS-RADS demonstrated a low miscategorization rate of 1.8%.
• Radiologists correctly identified final diagnoses in 71-88% of cases.
• Excellent inter-reader agreement was achieved for NS-RADS pathology (κ = 0.96) and muscle pathology (κ = 0.76).
• High accuracy rates (86-97%) were observed for classifying lesion severity.

Conclusions:

• The NS-RADS classification system is accurate and reliable for peripheral neuropathy across diverse conditions and reader experience levels.
• NS-RADS provides a standardized guideline for MRI reporting of PN, enhancing multidisciplinary communication.
