NYTimes.com : Urgent warnings by government experts about the risks of routinely using powerful CT scans to screen patients for colon cancer were brushed aside by the Food and Drug Administration, according to agency documents and interviews with agency scientists.After staying quiet for a year, the scientists say they plan to make their concerns public at an FDA meeting to discuss how to protect patients from unnecessary radiation exposure. The two-day meeting is part of a reassessment of the risks of routine radiology. The average lifetime dose of diagnostic radiation has increased sevenfold since 1980, driven in part by the increasing popularity of CT scans. Such scans can deliver the radiation equivalent of 400 chest x rays.
