A preliminary report on medical radiation exposures to the US population based on publicly available sources of data estimated that the collective dose received from medical uses of radiation has increased by Ͼ700% between 1980 and 2006. 1 Computed tomography (CT) has had an annual growth rate of Ͼ10% per year and accounted for Ϸ50% of the collective dose in 2006. Approximately 65% of the collective CT dose is from studies of chest, abdomen, and pelvis. In 2006, cardiac CT accounted for 1.5% of

Among nuclear medicine studies, cardiac imaging represented 57% of the number of studies and Ϸ85% of the radiation dose. 1
