After the scans, the research did show an increase in DNA damage in cells, as well as cell death. For their study, scientists at Stanford examined the cells of 67 patients who underwent a wide range of CT (or "computerized tomography") scans. Since cancer cells are more active than normal cells, the cancer cells take up more of the radiolabeled glucose and show up on the FDG-PET scan. Murphy's idea was to flood the body with antioxidants that neutralize free radicals prior to medical procedures such as CT scans, which use X-rays to image the body; the antioxidants would counter the damage from radiation. Non-small cell lung cancer (NSCLC) accounts for approximately 80% of new diagnoses of pulmonary carcinoma. After the scan, the facemask is removed and you may go home.
