"Superscan" on F18‑fluorodeoxyglucose Positron Emission Tomography - Computed Tomography [18‑F] FDG PET-CT

"Superscan" features have been described in 18F FDG PET-CT (F18 fluorodeoxyglucose Positron Emission Tomography‑Computed Tomography) scan; characterized by significantly increased uptake in one or more organ systems resulting in absent or decreased uptake in the organs which normally show physiological uptake. The importance of the awareness has evolved over the years in order to avoid false interpretation of scan findings as well as in determination of a high tumour burden. We present images of three patients who underwent 18F FDG PET-CT scan showing findings consistent with FDG PET-CT superscan.
