Radiation Dose from Common Imaging Examinations

This chart simplifies a highly complex topic for patients’ informational use, by outlining common imaging examination methods and their associated approximate effective radiation dose. The effective doses are typical values for an average-sized adult. The actual dose can vary substantially, depending on a person’s size as well as on differences in imaging practices. It is also important to note that doses given to pediatric patients will vary significantly from those given to adults, since children vary in size. Patients with radiation dose questions should consult with their radiation physicists and/or radiologists as part of a larger discussion on the benefits and risks of radiologic care.
