Ultrasound Imaging of the Brachial Plexus and Nerves About the Neck.

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.
