Sonographic Nerve Tracking in the Cervical Region: A Pictorial Essay and Video Demonstration

Abstract

Imaging of the nerves in the cervical region is more complicated than those of the extremities. Although high-resolution ultrasound enables the depiction of peripheral nerves' morphology and their associations with the adjacent soft tissues, precise identification of the nerves in the neck is still challenging. Familiarization with the cervical nerve tracking techniques can help interventional physiatrists explore/treat relevant entrapment syndromes, so does guiding proper electrode placement during nerve conduction studies. The present article integrates serial ultrasound images and videos to demonstrate how to scan brachial plexus, superficial cervical plexus, cranial nerves in the neck region, and certain branches of the major cervical nerves.
