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.
4 Οκτ 2012 · The major challenges posed by pregnancy, radiosensitive breast tissue, lactation, and an inability to easily exclude ovaries from the imaging field make female patients particularly vulnerable to medical imaging radiation exposure.
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.
When a pregnant woman with suspected appendicitis is referred for a CT scan, what should a radiologist do to minimize potential radiation risks? Pediatr Radiol. 2004;34:589–590. doi: 10.1007/s00247-004-1206-8.
Exposure to medical radiation from CT scans was associated with elevated risk of thyroid cancer (OR = 2.55, 95% CI = 2.36 to 2.75) and leukemia (OR = 1.55, 95% CI = 1.42 to 1.68). The elevated risk of thyroid cancer and leukemia in association with medical CT was stronger in women than in men.
30 Νοε 2022 · Moreover, cancer risks elevated with increase of radiation dose (OR, 33.31 [95% CI, 21.33 to 52.02]), and multiple CT scan sites (OR, 14.08 [95% CI, 6.60 to 30.05]). The risk of solid malignancy was higher than leukemia.
What is computed tomography? What can a person expect during a CT procedure? How is CT used in cancer screening? What is total-body, or whole-body, CT? What is combined PET/CT? Is the radiation from CT harmful? What are the risks of CT scans for children? What is being done to reduce the level of radiation exposure from CT?
