Abstract:
Magnetic resonance neurography (MRN) of the brachial plexus (BP) has witnessed significant technical advancements in recent years, with improved spatial and contrast resolution enabling greater demonstration of nerve detail and corresponding pathology. In this article, we provide an update on the technical considerations for MRN of the BP, including surface coils and advanced imaging sequences, and review the standard technical approach to investigating common BP pathology using MRN. Suggested imaging protocol modifications are discussed depending on common clinical scenarios of typical MRN BP referrals, and quintessential imaging findings of these pathologies are highlighted.
