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.
