Fluorodeoksüglükozun
Fluorodeoksüglükoos, commonly abbreviated as FDG, is a glucose analog used as a radiotracer in positron emission tomography (PET) imaging. It is structurally similar to glucose but with a fluorine-18 atom replacing a hydroxyl group at the 2-position of the deoxyglucose molecule. This substitution makes FDG metabolically trapped within cells once it enters the cellular pathway for glucose utilization.
The key principle behind FDG PET imaging lies in the differential uptake of glucose by various tissues.
FDG PET is widely employed in oncology for the detection, staging, and monitoring of a broad range
