Full Body CT scans-Risk of Radiation Exposure
"They promise to cut your risk of dying from cancer. Yet full-body CT scans themselves pose a real cancer risk, new calculations suggest. X-rays from a single full-body CT scan give a dose of radiation similar to cancer-associated radiation doses in A-bomb survivors, finds David J. Brenner, PhD, director of Columbia University's center for radiological research.
Richard L. Morin, PhD, chairman of the ACR's commission on medical physics, says that given lack of an established benefit, the risks Brenner identifies raise doubts about screening healthy people with full-body CT scans. "This paper is important in demonstrating explicitly that the risk from whole-body CT or any other diagnostic radiology exam is not zero," Morin tells WebMD. "It supports the thinking that screening whole-body CT scans of healthy individuals is not a wise course of action." "
