MR Imaging of Pediatric Nerve Disorders.

Evaluating pediatric nerve disorders is complex due to the small size of nerves and the intricacies of nerve anatomy. This article addresses key nerve pathologies in the pediatric population, focusing on both peripheral nerve and brachial plexus disorders. It discusses how MR imaging can classify and grade peripheral nerve injuries, assess the severity of nerve damage, and guide management decisions. Additionally, the article explores pediatric brachial plexus pathologies, highlighting MR neurography's (MRN's) ability to identify structural causes of thoracic outlet syndrome and classify brachial plexus birth injuries. As techniques continue to evolve, MRN's ability to provide detailed visualization of structural nerve changes and associated muscle effects with enhanced diagnostic accuracy, will further inform treatment strategies for these complex pediatric conditions.
