Uptake on PET: The uptake of 18F-FDG by tissues is a marker for the tissue uptake of glucose, which in turn is closely correlated with certain types of tissue metabolism. Tumors in general are more metabolically active than normal tissues and this difference in uptake is what makes PET scans possible. Tumors that have a higher metabolic rate will have more FDG uptake. Tumors that are less active havel less .
