MSK ultrasound is used to scan the nerve roots and brachial plexus. MSK ultrasound can be used for diagnostic and interventional purposes. For localizing the nerve roots one makes use of the bony landmarks of the different cervical segmental levels. This article defined a set of potential, relevant, specific anatomical landmarks and validated them anatomically. As an example, the transverse processes of C6 and C7 are shown in the image at the bottom this post.
