"For example, the pre-eminent PET radiotracer fluorodeoxyglucose (FDG) is comprised of a fluorine-18 isotope bound to 2-deoxy-2-glucose, an analogue to glucose. The 2-deoxy-2-glucose ligand is a substrate for the hexokinase/glucokinase enzymes involved in the early carbohydrate metabolism; thus, FDG is chemically linked to cellular metabolic activity 1. It serves as a particularly good tracer agent because it tends to stay "trapped" within metabolically active cells due to the absence of the hydroxide group ("deoxy-")."
