Fluorodeoxyglucose Overview

Fluorodeoxyglucose is a glucose analog. Its full chemical name is 2-fluoro-2-deoxy-D-glucose, commonly abbreviated to FDG. FDG is most commonly used in the medical imaging modality positron emission tomography : the fluorine in the FDG molecule is chosen to be the positron-emitting radioactive isotope fluorine-18, to produce18F-FDG. After FDG is injected into a patient, a PET scanner can form images of the distribution of FDG around the body. The images can...
