Antioxidants may help reduce the negative effects of X-Rays and CT Scans

12th April 2011

A unique formulation of antioxidants taken orally before X-Rays and CT Scans may help to minimise the cell damage during the procedure, a new study has shown.

Researchers at the University of Toronto and the University Health Network found that the amount of DNA injury reduced by as much as 50 per cent following the administration of these antioxidants during trials.

The study was completed in response to controversy over determining the cancer risk associated with medical imaging. The researchers wanted to explore a way to protect people from the potentially harmful effects of the important medical tool of X-Rays and CT Scans.

Lead researcher Kieran J Murphy, M.D. said: "Pre-administering this formula before a medical imaging exam may be one of the most important tools to provide radioprotection and especially important for patients in the getting CT scans."

The technique tested in the small study may also help radiologists and nurses, according to the University Health Network. The next step in the study will be clinical trials in Toronto.

Radiation released during X-Rays may be harmful due to the effect the rays have with water in the body.
