Abstract:
This review focuses on the critical role of MR neurography (MRN) in diagnosing and managing peripheral nerve injuries (PNIs). It emphasizes the ability of imaging to differentiate injuries that may heal spontaneously from those requiring surgery, using classification systems like Neuropathy Score Reporting and Data System with imaging findings corresponding to established electrodiagnostic grading systems. MRN also evaluates skeletal muscle denervation and is useful for differentiating pre-ganglionic from post-ganglionic traumatic injuries. MRN is an integral component of optimizing care for patients with PNI.

The nerve is a bundle of axons that serves as the communication highway in the PNS. Each nerve is ensheathed in a protective layer of connective tissue called the epineurium. This outermost layer safeguards the nerve and supports the...
