Exposure to Low-Dose Ionizing Radiation from Medical Imaging Procedures

The use of medical imaging procedures has been increasing, and this study estimated the exposure of U.S. patients to low-dose ionizing radiation from these procedures. The exposure was substantial, largely because of radiation from computed tomography and nuclear imaging. The highest average effective dose was attributable to myocardial perfusion imaging, and most imaging occurred in outpatient settings. These data indicate that the use of imaging can result in high radiation doses.
