I am going to have an epidural tomorrow in my lower lumbar spine. I signed a paper approving the use of a special X-ray but now I’m wondering if I did the right thing. They told me it would have a higher dose of radiation but it gives the surgeon a better view in there. Did I do the right thing?

You may be referring to a special imaging technique called fluoroscopy. It is a form of X-ray that sends images of your spine to a computer. The surgeon can then see inside your body while performing the operation.

This imaging method makes it possible to direct the needle for the epidural steroid injection (ESI) to the exact spot needed. Since there are vital structures in this area, accuracy is important.

A small error can result in puncture of the blood vessels. It’s even possible that the needle could penetrate the gastrointestinal tract. Fluoroscopy decreases the risk of complications from improper needle placement.

It is true that there is increased exposure to radiation with this type of imaging. But the procedure also takes less time with the improved visualization. The surgeon will make every effort to limit exposure time because the medical staff present is also exposed. And they are exposed at every use, whereas the patient is exposed one time.

You can reconsider your decision and discuss this with the surgeon before the procedure. Using fluoroscopy to apply the ESI directly to the inflamed nerve gives the best results. Pain relief may be an acceptable trade off to you for the amount of radiation dose you will be exposed to.
