Course Description
Ionizing radiation used in medical imaging provides both benefits and risks to patients and healthcare providers and accounts for more than half the radiation exposure experienced by the population in the United States. The word radiation evokes fear for many. Radiation can cause cancer in high doses, levels much higher than those used for routine x-rays or a single computed tomography (CT) scan. Misunderstanding about radiation and medical imaging thrives among both the public and healthcare providers. The risk of developing cancer as a result of exposure to radiation depends on the part of the body exposed, the individual’s age at exposure, and the individual’s sex. It is assumed that the risk for adverse health effects including cancer is proportional to the amount of radiation dose absorbed and that there is no amount of radiation that is completely without risk. There is considerable uncertainty regarding the risk estimates for low levels of radiation exposure as commonly experienced in diagnostic radiology procedures. However, one must also balance the risk of NOT performing an examination, which might result in missing a diagnosis and/or initiating treatment too late to improve the medical outcome. This review examines the data regarding the risk of cancer from ionizing radiation and suggests measures to consider when imaging both adults and children.
