A CT scan of the abdomen (belly) and pelvis exposes a person to about 10 mSv. A PET/CT exposes you to about 25 mSv of radiation. This is equal to about 8 years of average background radiation exposure. Keep in mind that these are estimates for an average-sized adult.
Common types of CT scans and the amount of radiation you would absorb from them include: Belly and pelvis: 10 mSv, equal to about 3 years of background radiation. Colonography: 6 mSv, equal...
Here are some approximate comparisons of background radiation and effective radiation dose in adults for several radiology procedures described on this website. These values can vary greatly, depending on the size of the patient and the type of imaging technology being used.
The main risks associated with CT scans are incidental results, leading to unneeded, possibly invasive, follow-up tests that may present additional risks and the increased possibility of...
30 Σεπ 2021 · Patients want to know if radiation from mammograms, bone density tests, computed tomography (CT) scans, and so forth will increase their risk of developing cancer. For most women, there's very little risk from routine x-ray imaging such as mammography or dental x-rays.
The overall median effective doses ranged from 2.1 milli-Sieverts (mSv) for a routine head CT (interquartile range [IQR] 1.8–2.8) to 31 mSv (IQR 21–43) for a multiphase abdomen and pelvis CT.
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.
