Ask Your Health Question and Get an Answer ASAP
Hi. Dr Rick here. I completed an Internal medicine internship in NYC and have two decades of clinical experience. How can I assist you today?
This is a term used when discussing the results of a PET scan.
FDG avid refers to a type of glucose (sugar) this is linked with radioactive fluorine. This radioactive sugar is found in much higher concentrations in areas of your body that are using lots of energy, such as tumors, and shows up on the PET scan.
If these FDG avid areas are located in a part of your body that would not normally be expected to use a lot of energy this means that something is wrong, usually that cancer is present.
Of course, your doctor is the best person to explain what these FDG avid areas might mean in your particular situation.
Does this make sense to you?
