Article Figures & Data
Figures
- Fig 1.
Axial CT fluorscopic image demonstrates the approach used to access the neural foramen. Needle tip is located along the posterior foramen, well away from the vertebral vessels but directly adjacent to the exiting nerve root.
- Fig 2.
After its injection, the contrast material is noted to travel along the posterior aspect of the nerve root within the neural foramen. In many cases, transforaminal contrast enhancement is not seen, as the material stays around the ganglion and extraforaminal nerve.
