- Understanding Radiation Risk From Imaging Tests
An imaging test is a way to let doctors see what’s going on inside your body. These tests send forms of energy (like x-rays, sound waves, radioactive particles, or magnetic fields) through your body. Your body tissues change the energy patterns to make an image or picture.
The amount of radiation exposure from an imaging test depends on the imaging test used and what part of the body is being tested. For instance: A single chest x-ray exposes the patient to about 0.1 mSv.
29 kwi 2022 · X-rays help doctors detect cancer in the bones as well as in organs such as the stomach, kidneys and lungs. Breast X-rays (called mammograms ) can detect breast cancer. X-rays may also be used to find out how well a cancer treatment is working, to help your care team plan for a cancer surgery, and to provide visuals to assist with the placement ...
30 wrz 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.
On completion of this article, you should be able to (1) recognize the doses of common medical imaging studies, (2) recognize which patients may be at increased risk from radiation, and (3) be familiar with the evidentiary base for determining excess cancer risks from low-dose radiation.
X-rays use low doses of radiation to create pictures of the inside of your body. Credit: iStock. If you have a symptom or a screening test result that suggests cancer, your doctor will find out whether it is due to cancer or some other cause. There is no single test that can diagnose cancer.
