JAMA. 2012;307(22):2400-2409
as many of you know from being exposed to my rantings, i am very concerned about excessive iatrogenic radiation exposure. (i believe exposure to my rantings are less toxic than the radiation).
article in jama looks at 6 integrated health care delivery systems with 1-2 million people over 15 years. effective doubling of radiation exposure in this period , esp with CT scans (increased 3-fold). calculated anticipated 2% increased risk of cancer from this increased exposure (this may be an argument to dissuade some patients who seek a CT scan unnecessarily).
