PET Scan
A positron emission tomography (PET) scan of the heart is an imaging test that uses specialized dye to allow your doctor to view problems with your heart.

The dye contains radioactive tracers, which concentrate on areas of the heart that may be injured or diseased. Using a PET scanner, your doctor can spot these areas of concern.

A heart PET scan is typically an outpatient procedure.

RISKS
While the scan does use radioactive tracers, your exposure is minimal. The exposure level is too low to affect the normal processes of your body and is not regarded as a major risk.

*If you are pregnant, believe you may be pregnant, or are nursing, tell your doctor. This test may be unsafe for your unborn or nursing child.

How to prepare for your test:
Your doctor will provide you with complete instructions about preparing for your heart PET scan. Alert your doctor and technician of any medications you may be taking.

If your appointment is after 12 noon, you may have a light breakfast (toast or bagel with jelly and juice. Or you may have an early lunch 4 hours before your appointment time.

DO NOT EAT OR DRINK anything with caffeine 24 hours prior. This includes coffee, tea, soda or chocolate. DO NOT EAT OR DRINK anything that says “decaffeinated” or “caffeine free”. You will, however, be able to drink plenty of water the day before and morning of your test to help administer the IV.

Be sure to wear comfortable clothes (button down shirt) and comfortable shoes, as you MIGHT exercise on a treadmill.

Bring a list of medications that you are currently taking and a snack with something to drink.
