RADIATION EXPOSURE FROM MEDICAL IMAGING: What Patients Should Know

http://www.ucsf.edu/news/2012/06/1214...
A study led by researchers at the University of California, San Francisco (UCSF) and Group Health Research Institute, shows that medical imaging is increasing even in health maintenance organization systems (HMOs), which don't have a financial incentive to conduct them.

Published this week in the Journal of the American Medical Association (JAMA), the study is the first to look at how radiation exposure from CT scans and other procedures has grown within large integrated health care systems.
