Positron emission tomography (PET) scan is a diagnostic test that uses small amounts of radioactive chemical to show activity within the body on a cellular level. It helps doctors see how the organs and tissues inside your body are functioning. This test can be used to help diagnose or to evaluate how well a treatment is working.
PET scans are usually done to detect cancer, to evaluate the effectiveness of a cancer treatment therapy, to identify heart disease or a brain disorder. They measure blood flow, oxygen use, how your body uses sugar and much more. It is usually an outpatient procedure and takes about 2 hours.
PET scans can detect very early changes in your cells. CT scans and MRIs can only detect changes later, as a disease alters the structure of your organs or tissues. Sometimes a combination of two scans, CT and PET, is used to get a more well-rounded picture of the health issue.
