radiation exposure from fluoroscopy

April 10, 2007 By Arthritis Center

Question

My Dr uses fluoroscopy when doing knee injections, he billed me for 32 units of fluoro. How much radiation am I being esposed to? Where can I find out more information on this procedure?

Answer

The short answer is that I really don’t know who would have the info in a form that a lay person would understand. You might try the government agency OSHA. They regulate x-ray facilities. In general, x-rays of extremities (hands, knees) entail much less total body radiation than chest x-rays, abdominal x-rays or spine x-rays. Certainly, there is no comparison to CT scans where radiation levels are much higher.
