What to Expect Prior to Test
  • Wear comfortable clothes.
  • Do not eat or drink anything, except water, for at least four hours before the scan.
  • Check with your doctor about taking your regular medicines.
  • If you have diabetes , ask the doctor for specific diet recommendations for the test day, since this can affect your results.

Description of Test

A nurse or technologist will give you a radioactive substance. This may be done through an injection, or in some cases, you will be asked to breathe in a gas. It will travel through your blood to the area of the body being studied. It takes 30-90 minutes for the substance to be absorbed by the tissue. Once the substance has been absorbed, the scan can take place.

You will lie on a table and be moved into a machine that looks like a large, square doughnut. This machine detects and records the energy levels from the substance that was injected earlier. The images are viewed on a computer monitor. The scan lasts about 30-45 minutes. You may be asked to perform specific tasks before or during the test. For example, during a heart PET scan, you may be asked to walk on a treadmill.

After Test

Drink plenty of fluids to help the radioactive substance pass from your body.

How Long Will It Take?

At least two hours

Will It Hurt?

Except for the pinprick from the injection, a PET scan is a painless procedure. People who are claustrophobic (uncomfortable in closed or tight spaces) may have some anxiety .
