Overview

F18 fluorodeoxyglucose is a glucose analog labeled with fluorine 18 used widely for PET imaging of metabolic activity.

Properties

FDG accumulates in tissues with high glucose metabolism; positron emission allows high resolution PET imaging and quantitative SUV analysis.

Uses

Used for oncologic staging and response assessment, infection and inflammation imaging, and selected neurologic and cardiac applications.

Safety

Radiation dose is moderate; ensure appropriate fasting and glucose control prior to injection and follow pregnancy and breastfeeding precautions.
