It has been more than a decade since two articles were published that drew the attention of the wider community to the radiation exposures associated with pediatric computed tomography (CT) (1,2). One of the articles pointed out that most pediatric CT scans were being performed with adult-based settings, resulting in a higher radiation dose than was necessary in children who underwent CT scans (2). The other article (1) provided the first quantitative estimates of radiation risks associated with pediatric CT. The following day, the story hit the front page of USA Today, and the world of CT changed dramatically.
