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.
The low doses of radiation used for imaging tests might increase a person’s cancer risk slightly, but it’s important to put this risk into perspective. Here are answers to some of the more common questions people have about radiation risks linked to imaging tests.
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.
30 Σεπ 2024 · Calculate your dose and estimate cancer risk from studies including CT scans, x-rays, nuclear scans and interventional procedures.
Radiation exposure from a CT scan . If the CT is normal, does that mean it should not have been done? A normal CT provides valuable information. If there is enough concern, then CT should be done whether it turns out positive or negative. Are there alternatives to CT? If you face a serious emergency condition that requires a CT, donot hesitate ...
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.
