Rapid advances have been made in pediatric radiological imaging by means of cardiac catheter angiography, CT, and nuclear medicine. These imaging modalities, however, impart a radiation dose to children. Although the presence of radiation exposure to children has long been recognized, there is a lack of readily accessible information to address radiation risks and radiation dose assessment for pediatric cardiologists, radiologists, and other pediatric health care providers. This article provides a science advisory for such procedures and practical information on age-dependent radiation risks and radiation dose associated with cardiac catheterization, cardiac CT, and nuclear medicine.
