CT-Guided Cervical Nerve Root Blocks

I have three questions for radiologists who perform spinal injections for pain management.

1. How many people regularly do cervical nerve root blocks?
2. Are you using CT or conventional fluoro?
3. If you are using CT, do you use contrast to confirm needle position?

It would be great for people to comment on the blog, but you can also email me directly.

    We exclusively use ct to giude cervical blocks, and perform about 5 cases per day in outpt setting with devoted ct scanner, techs, and 4 nurses / holding area. We use diluted contrast to confirm location prior to injection of medication.
