Spinal (Back & Neck) Injections

What is an injection?

Spinal Injections involve a Radiologist (specialist doctor) using CT to guide the injection of a needle containing a corticosteriod (“a steriod”) and/or local anesthetic into the area of interest within the spinal column or joint. This is usually used to help relieve back or muscle pain caused by arthritis, strain or impingement a nerve. In conjunction with your referring Doctor, the performing Radiologist will consider your clinical symptoms to determine the type and location to administer the injection.
