Answer to Question #12077 Submitted to "Ask the Experts"
Category: Medical and Dental Patient Issues — Diagnostic X Ray and CT
The following question was answered by an expert in the appropriate field:
I recently had an abdominal/pelvic computed tomography (CT) scan with contrast and a barium swallow. The report for the CT scan shows that Omnipaque 240 and 350 were used and barium was used for the barium swallow. I am wondering whether these are radioactive drugs and if they themselves add to the radiation received from the actual procedure.
The drugs are contrast agents, used to produce better images. They are not radioactive and do not contribute any radiation dose.
