Melbourne: CT scans generate up to one third more radiation than needed to yield a clear diagnostic image, thus exposing patients to an increased risk of cancer, according to a study in Australia. The findings have emerged amid concerns about the growth in referrals for CT scans and as radiation safety experts and radiologists prepare a national monitoring scheme to keep radiation doses to the minimum necessary.
``This results in a general dose-saving to the individual and a reduction in the public health risk of an expanding population of patients being imaged,`` the Age quoted Wallace as saying. ANI
