Positron Emission Tomography of the Chest
WHAT YOU NEED TO KNOW:
A positron emission tomography (PET) scan is used to take pictures of your chest. A small amount of radiation, called tracer, is put into your body before the PET scan. The tracer shows how chemicals, such as glucose (sugar), are working in your tissues. A PET scan of your chest will show the blood flow through your heart. A PET scan may show an abnormal growth, such as a tumor. It may be used to show if cancer has spread. A PET scan may show disease or damage to your chest, lungs, heart, or esophagus.
Follow up with your healthcare provider as directed:
You may need to return to go over the results of your PET scan. Write down your questions so you remember to ask them during your visits.
Drink liquids as directed:
You may need to drink extra liquids after your PET scan. This will help flush the tracer out of your body. Ask your healthcare provider how much liquid to drink each day and which liquids are best for you.
Contact your healthcare provider if:
- You feel dizzy.
- You have questions or concerns about your PET scan, condition, or care.
Seek care immediately or call 911 if:
- You have trouble breathing or you cough up blood.
- You have chest pain or discomfort in your chest that feels like squeezing, pressure, or fullness.
- You have chest pain or discomfort that spreads to your arms, jaw, or back.
- You have chest pain that lasts for more than a few minutes or returns.
- You have nausea or you are sweating for no reason.
