Computed tomography (CT) scanning, which was introduced for imaging the head in 1972 and became widely available for imaging the rest of the body by the early 1980s, has revolutionized the practice of medicine and surgery. This technology, for which the Nobel Prize was awarded in 1979, has been used to diagnose and guide the management of diseases affecting every part of the body, improving quality of life and saving countless lives. Two articles in this issue of JAMA,1- 2 however, point out the complexities involved in deciding whether to extend the use of CT scanning from diagnosis to screening and in determining whether the current use of CT scanning is appropriate or excessive.
