Chapter 15 - High-Resolution Magnetic Resonance Neurography and Anatomy of the Cervical Plexus

Abstract

The cervical plexus is formed by the ventral rami of the C1–C4 spinal nerves. MR neurography is an excellent tool for identifying the ventral rami, the communicating loops, and the superficial and deep branches of the cervical plexus. A combination of high-resolution two- and three-dimensional (2D and 3D) sequences and functional techniques, preferably on 3.0T scanners, allows those thin neck nerves to be followed.
