Soaring CT-based radiation exposure points at self-referral

March 2, 2009 Diagnostic Imaging. Soaring CT-based radiation exposure points at self-referral By H.A. Abella The U.S. population underwent seven times as much ionizing radiation exposure from medical imaging in 2006 as it did in 1987, mainly from CT, according to a study released at the 2009 National Council on Radiation Protection and Measurements in Bethesda, MD. Overutilization due to self-referral appears to bear some blame. Findings of the NCRP report No. 160, released March 3, serve as follow-up to a preliminary report released in April 2007 that suggested the amount of radiation dose experienced by the U.S. public from such exams could have increased more than 600% in the last two decades.
