Exposure to ionizing radiation is associated with a long-term risk of health effects, including cancer. Radiation exposure to the U.S. population from cardiac imaging has increased markedly over the past three decades. Initiatives to reduce radiation exposure have focused on the tenets of appropriate study "justification" and "optimization" of imaging protocols. This article reviews ways to optimally reduce radiation dose across the spectrum of cardiac imaging.
