【Introduction】   Glucose is one of the metabolic energy substances in the human body. Malignant tumor cells metabolism of glucose far exceeds that of normal cells. The properties of deoxysugar (DG) labeled with fluoride [18F] are basically the same as glucose. Using PET-CT to capture the [18F]FDG metabolism of human tissues can detect the activity of tumor cells, so it is known as "the molecule of the 21st century."

【Advantage】   Indicated for early diagnosis of tumors, tumor staging, and evalsuation of tumor treatment.
