Imaging tests Certain types of imaging tests, such as x-rays, CT scans, and nuclear medicine tests such as PET scans and bone scans expose people to low levels of radiation in order to create internal pictures of the body.

Some imaging tests, such as MRI and ultrasound do not expose people to ionizing radiation.

The amount of radiation varies depending on the test. For example, the exposure from a 2-view chest x-ray is about 0.

MEDICAL USES OF RADIATION EPUB

These are for treatment of disease or cancer and are commonly called therapy.
