Primary Care Corner with Geoffrey Modest MD: Radiation exposure

By: Dr. Geoffrey Modest 

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).

An article in JAMA looks at 6 integrated health care delivery systems with 1-2 millions 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).
