Day of the scan

It is important to arrive early to your appointment. Gallium-68 is a radiopharmaceutical, which decays (loses its radioactive strength) in a relatively short period of time, so it is important to get to your appointment early with plenty of time. Please plan appropriately if you expect that there might be traffic or other delays. If you arrive late, you may not be able to have the scan, as the Gallium-68 may have decayed too much.

A Gallium-68 PET/CT scan uses an injection including Gallium-68 that is made specifically for you on the day of your scan by a radiopharmacy. There are certain requirements that the drug must meet before it can be injected into your body. If the drug that was made for you does not meet those requirements, it will not be used. Depending upon the radiopharmacy’s availability, they may attempt to make another injection for you on that same day to replace the first one. The PET/CT center will contact you if there are any changes in your scan appointment.

It is recommended to wear loose-fitting and comfortable clothing to your appointment. Depending upon the scan location, they may ask you to change into a hospital gown and take off your jewelry.

A Gallium-68 PET/CT scan is conducted on a PET/CT machine. The healthcare provider who is in charge of conducting the scan will tell you how to position yourself for the scan. Tell them if you have any preferences or concerns about how you will be positioned. Since the scan time can vary from 20-40+ minutes (depending upon the PET/CT machine), it is important to position yourself in a comfortable way (arms up vs arms at your side, etc.). Once you have picked a position, you cannot change it during the scan.
