What is a PET/CT scan?
A PET/CT scan combines positron emission tomography (PET) and computed tomography (CT) images. PET images show how organs and tissues in the body are working. CT images show details of body anatomy such as vessels, lymph nodes and organs. When PET and CT scans are combined, the fused images help doctors detect cancer, heart problems, neurological conditions such as Alzheimer’s, and other central nervous system disorders.
What to Expect During Your PET/CT Exam
In preparation for a PET/CT exam, you will receive a small injection of radioactive tracer. You will then rest comfortably while the radioactive tracer moves through your body for approximately 60 minutes. Then we take you to the scanner for your exam, which lasts anywhere from 20-45 minutes, depending upon the body area being scanned.
After your scan, be sure to drink plenty of water to help safely flush the radioactive tracer from your body. PET/CT scans are considered low risk and normal activity can be resumed right away, however, if you are breast feeding or will be around young children, please speak with the technologists about precautions to take.
