PET/CT Myocardial Sarcoidosis Scan

Your doctor has suggested you have a PET/CT scan of your heart as part of the evaluation at National Jewish. A PET scan is a shortened name for positron emission tomography. A PET scan views functioning tissues in the body. A CT or CAT scan is a shortened name for computerized tomography. A CT scan takes pictures of the inside of the body. The pictures are more detailed than a typical x-ray. The type of PET/CT scan your doctor recommended will show detailed images and functioning tissues of your heart.

The PET/CT scan can help determine if sarcoidosis has affected your heart. Your doctor will use this information to determine the best treatment for you.


Preparing for the Test

  • Avoid carbohydrate sources for 24 hours prior to this test. No stress activity 24 hours prior to your test.
  • Do not eat or drink after midnight the day the test is scheduled. You may drink water only.
  • You will remove some clothing. You will be given a gown to wear.
  • Let the technologist know if you are pregnant, nursing or diabetic.

During the Test

The Nuclear Medicine Technologist will explain the PET/CT scan to you before you start. Ask questions if you don't understand.

The technologist will start an IV in your arm. You will feel a prick when the IV is started. The IV will be used to give you a liquid radioactive tracer and the IV will be removed after the injection. This will help view the functioning tissues of the heart during the scan. You will sit quietly on a recliner for 1 hour after getting the tracer.

After this wait you will have the PET/CT scan. The PET/CT scan does not hurt. During the PET/CT scans you will lie still on a padded table. The technologist will give you instructions during the test. You will be asked to raise your arms above your head during the scan.


After the Test

You can resume normal activities after the PET/CT scan.


Length of the Test

A PET/ CT scan takes about 1 & 1/2 to 2 hours.
