Radiation Concerns Rise With Patients’ Exposure
New York Times

Even in health care systems in which doctors do not bill for each test they administer, the use of diagnostic imaging like CT and PET scans has soared, as has patients’ radiation exposure, a new study has found.

The study, published online on Tuesday in The Journal of the American Medical Association, says that while advanced medical imaging has undoubted benefits, allowing problems to be diagnosed earlier and more accurately, its value needs to be weighed against potential harms, which include a small cancer risk from the radiation.
