Before the scan

Because somatostatin analogs such as lanreotide (Somatuline®) or octreotide (Sandostatin®) may affect the results of your scan, it is best to schedule your Gallium-68 PET/CT at the end of the somatostatin analog cycle and right before your next somatostatin analog injection.

Unlike other PET scans, a scan with Gallium-68 does not require you to fast or perform any special bowel preparation. However, there may be situations in which your healthcare provider will still recommend a fast or a special bowel preparation; this may be based upon where your tumor(s) are located. Always follow the directions provided to you by your healthcare provider.

A Gallium-68 PET/CT scan is done in a single day; however, you may need to be at the scan location for at least 2-3 hours. Speak with your healthcare provider to learn more, as timing depends upon a number of different factors specific to the scan location.

Speak with your healthcare provider about any medicines you may be taking, or if you are pregnant. Your healthcare provider will help you decide if a Gallium-68 PET/CT scan is right for you.
