The Gallium scan is a test used to detect inflammation.
Inflammation can be an indication of tumors or infections.
It is often used to assess and follow patients with Hodgkin's disease and Non-Hodgkin's lymphoma . They will give you an injection of the gallium which will not take long. You will also be given instructions on what to do the night and morning before the scan. This often includes not eating beforehand. You will be told to report back to the scan department 2 to 5 days after the injection for the scan.
