Abstract
CT-guided injection and radiofrequency ablation (RFA) of the C2 dorsal root ganglion (DRG) is a safe and effective treatment for cervicogenic headache arising from C1-C2 joint arthritis. The C2 nerve root is unique in that it lacks a motor component; RFA can be performed with pain relief in exchange for occipital numbness. This video article outlines the imaging anatomy and technical considerations of this procedure.
