We are constantly exposed to radiation from a number of sources, including radioactive materials in our environment, radon gas in our homes, and cosmic rays from outer space. This is called background radiation and it varies across the country.
The average American is exposed to about 3 mSv millisieverts of radiation from natural sources over the course of a year.
A millisievert is a measure of radiation exposure. But background radiation exposure varies throughout the United States, and the world.
The largest source of background radiation typically about 2 mSv per year is radon, a natural gas found in our homes. Radon levels vary greatly from one part of the country to another. So, people living in the higher parts of New Mexico and Colorado are exposed to more radiation per year about 1. And a hour airline flight increases cosmic ray exposure by about 0. 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:. Keep in mind that these are estimates for an average-sized adult. Studies have found that the amount of radiation you get can vary a great deal. If you have concerns about the radiation you may get from a CT scan, PET scan, or any other imaging test that uses radiation, talk to your health care provider. You may also want to know what you and your health care provider can expect to learn from it. The best advice at this time is to get only the imaging tests that are needed and try to limit your exposure to all forms of radiation.
For example, a lead apron can be used to protect parts of your chest or abdomen from getting radiation, and a lead collar known as a thyroid shield or thyroid collar can be used to protect your thyroid gland. You may also want to keep a medical imaging record to track your own history of imaging tests and share it with your health care providers.
This may help prevent repeat tests from being ordered. English and Spanish examples of imaging records for adults can be found online at www. Children are more sensitive to radiation than adults. Because of this, health care providers are careful to reduce radiation exposure to pediatric patients for imaging tests that use radiation.
Still, parents can and should ask questions before any imaging tests are done. An English version for children can be found online at www.Hypnosis mic song list
Radiation experts believe that if imaging tests do increase the risk of cancer, the increase in risk is likely to be very small. Most studies on radiation and cancer risk have looked at people exposed to very high doses of radiation, such as uranium miners and atomic bomb survivors.
The risk from low-level radiation exposure is not easy to calculate from these studies. We do know that children are more sensitive to radiation and should be protected from it as much as possible. Because radiation exposure from all sources can add up over a lifetime, and radiation can, indeed, increase cancer risk, imaging tests that use radiation should only be done for a good reason.Grin mining
In many cases, other imaging tests such as ultrasound or MRI may be used. The American Cancer Society medical and editorial content team. Children and Radiation Safety. March 30, Diagnostic imaging lets doctors look inside your body for clues about a medical condition.
A variety of machines and techniques can create pictures of the structures and activities inside your body. The type of imaging your doctor uses depends on your symptoms and the part of your body being examined. They include. Many imaging tests are painless and easy.Single nozzle inkjet
Some require you to stay still for a long time inside a machine. This can be uncomfortable. Certain tests involve exposure to a small amount of radiation.
For some imaging tests, doctors insert a tiny camera attached to a long, thin tube into your body. This tool is called a scope. The doctor moves it through a body passageway or opening to see inside a particular organ, such as your heart, lungs, or colon.
These procedures often require anesthesia. Diagnostic Imaging Also called: Imaging.

Diagnostic Imaging -- see more articles.Radiology may be divided into two different areas, diagnostic radiology and interventional radiology. Doctors who specialize in radiology are called radiologists.
Diagnostic radiology helps health care providers see structures inside your body. Doctors that specialize in the interpretation of these images are called diagnostic radiologists.
Using the diagnostic images, the radiologist or other physicians can often:. Interventional radiologists are doctors that use imaging such as CT, ultrasound, MRI, and fluoroscopy to help guide procedures.
The imaging is helpful to the doctor when inserting catheters, wires, and other small instruments and tools into your body. This typically allows for smaller incisions cuts. Doctors can use this technology to detect or treat conditions in almost any part of the body instead of directly looking inside of your body through a scope camera or with open surgery. Interventional radiologists often are involved in treating cancers or tumors, blockages in the arteries and veins, fibroids in the uterus, back pain, liver problems, and kidney problems.
The doctor will make no incision or only a very small one. You rarely need to stay in the hospital after the procedure.

Magnetic resonance imaging MRI is a noninvasive medical examination that does not use ionizing radiation X-rays. The MRI machine uses a large magnet and a computer to take pictures of the inside of your body.
The scan usually takes between 45 to 60 minutes. Ultrasonography, which is sometimes called sonography, uses high-frequency sound waves and a computer to create images. The primary use of breast ultrasound today is to help diagnose breast abnormalities detected during a physical exam such as a lump and to characterize potential abnormalities seen on mammography or breast MRI.
C-View images may be used with tomosynthesis in the screening and diagnosis of breast cancer, eliminating the need for a separate 2D exposure. The radiation dose with tomosynthesis and C-View offers the clinical benefits of tomosynthesis at about the same average dose of 2D digital mammograms in the USA.
Radiologists read the mammograms for early detection and diagnosis of breast diseases in women. Stanford also uses computer-aided detection CAD on the mammograms, which uses a computer program and neural networks to find cancer. A procedure in which contrast dye is used during mammography to identify the cause of spontaneous nipple discharge.
A specific type of imaging that uses a low-dose x-ray system to examine breasts and aid in the early detection and diagnosis of breast diseases in women. Magnetic resonance imaging is used to help guide the radiologist's instruments to the site of the abnormal growth. Tissue samples are then removed with a hollow needle called a core biopsy.
A special mammography machine uses X-rays mammograms to help guide the radiologists instruments to the site of the suspicious imaging findings. Tomosynthesis uses low dose x-rays to take mammogram images of the breast, and shows only a few layers of the breast at a time.
