PET/CT is a painless, relaxing procedure. You should plan to spend two to three hours at the imaging center.
On the day of your scan, dress in warm comfortable clothes. Avoid clothes with metal in them such as metal buttons, rivets or underwires. Do not wear jewelry.
When you arrive that the center, you will need to register. After registration, the PET/CT technologist will escort you to the PET/CT scan area. The technologist will explain the procedure and ask you about your medical history. This information is needed by the doctors who will be interpreting your scan.
After that, the technologist will insert an IV into a vein in your arm or the back of your hand. The technologist will also take a blood sample to determine the amount of sugar in your blood. Next the technologist will inject the radioactive sugar into your body through the IV. Once the sugar is injected, you will rest quietly for about an hour while your body takes up the sugar. During that time you can read or just relax.
Much of the radioactive sugar will end up in the urine in your bladder. So after the 45 minute rest period, we will take you to use the restroom. Next, the technologist will take you to PET/CT scanner, which consists of a bed that moves through a tube that is about 2 Ѕ ft in diameter and 5 ft long. The technician will provide you with pillows and pads to help you get comfortable. The PET/CT scan will take about 30 minutes. During that time it is CRITICAL that you lay as still as possible.
Once the scan is completed, you will be free to go. After you leave, you can go about your daily activities as normal.
