Fluorodeoxyglucose

Fluorodeoxyglucose (FDG) is a special radioactive sugar used in medical imaging, particularly in PET scans. It mimics glucose, which cells naturally use for energy. Because cancer cells often consume more glucose than normal cells, FDG accumulates more in affected areas. When injected into the body, a PET scanner detects the radioactive signal from FDG, helping doctors identify and locate tumors, infections, or other abnormalities. This technology provides valuable insight into how tissues function in real-time, aiding accurate diagnosis and treatment planning.
