Radiation Dose to Adults From Common Imaging Examinations. For the most current information, visit radiologyinfo.org. 05.22. Note: This chart simplifies a highly complex topic for patients’ informational use. The effective doses are typical values for an average-sized adult.
Doctors use "effective dose" when they talk about the risk of radiation to the entire body. Risk refers to possible side effects, such as the chance of developing a cancer later in life. Effective dose considers how sensitive different tissues are to radiation.
Are imaging examinations safe? Exposure to medical imaging that uses X-rays or gamma rays (radiographs, fluoroscopes, CT scans, and nuclear medicine) potentially may increase the risk of a cancer occurring later in life. Because the doses of radiation given in medical imaging are low, it is not possible to provide an accurate estimate of risk.
Diagnostic Imaging. Radiation exposure from a CT scan. This handout will help to answer your questions about CT scans. If you have other questions, please ask one of our staff and they would be glad to explain things to you. What is a CT? CT, also known as a CAT scan, sends X-Rays through the patient’s body to form a picture of the body.
The UCSF Risks of Radiation page describes the risk of repeated CT scan imaging in the context of everyday, normal radiation exposure.
17 Σεπ 2015 · In. recent years, use of computed tomography (CT) has increased dramatically. Increased dose from radiography, and CT in particular, has led many physicians and patients to question the cancer risks and overall safety of modern imaging.
