What does FDG stand for?

• A. Fluorodeoxyglucose
• B. Fluorodeoxyglycol
• C. Fluorinated deoxyglucose
• D. Fluoroglucose

Answer: (A)

FDG stands for Fluorodeoxyglucose. This radiotracer is basically glucose with two key tweaks: the 2-hydroxyl is replaced by hydrogen (deoxy), and a radioactive fluorine-18 atom (fluoro) is attached. In PET imaging, cells take up FDG like glucose, but after phosphorylation it gets trapped as FDG-6-phosphate, so tissues with higher metabolic activity light up on the scan. That makes FDG-PET a powerful tool for detecting cancers, assessing inflammation, and evaluating brain/metabolic activity. The other phrasings aren’t standard names for this compound. Fluorodeoxyglycol isn’t a recognized chemical name, fluorinated deoxyglucose isn’t the conventional nomenclature used in practice, and fluoroglucose would imply a different, less precise label, not the established FDG designation.
