WebOct 23, 2024 · FDG is a radioactive sugar that is used in PET imaging. The idea is that FDG is taken up more in abnormal tissues then normal ones. That is, abnormal tissues use glucose or sugar more then normal ones. This is reflected in PET scans as more uptake and a hotter or brighter tissue on the scan. Is FDG uptake always abnormal? WebThe majority of cases demonstrating focal FDG uptake in prostate were benign and no PET/CT finding could reliably differentiate benign from malignant lesions; however, when discrete focal FDG uptake without coincidental calcification is seen, particularly in the peripheral zone of the prostate, further clinical evaluation is recommended.
