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.
