This review describes techniques for sonographic evaluation of the brachial plexus and multiple regional nerve branches in the neck, essential for successful implementation of neurosonology in the neck. High-frequency ultrasound transducers have the ability to produce superior, high-resolution images, allowing for superb depiction of nerve fascicular anatomy. Sonographic appearances of normal nerve anatomy and nerve-specific pathology are reviewed. Benefits and limitations of ultrasound nerve imaging compared with magnetic resonance imaging are discussed.
