Study's authors recommend fewer unnecessary CT scans

A new study finds, not only are CT scans delivering higher than expected radiation doses, but that they vary widely even among the same types of examinations. The issue is important because over the first two decades the use of diagnostic CT scans has skyrocketed-- from 3 million scans nationwide in 1980 to 70 million in 2007.

Authors say doctors should reduce the number of unnecessary CT scans.
