title: FDG PET/CT Appearance of Radiation Nephritis.
abstract: It is often challenging to assess renal activity on FDG-PET/CT due to intense physiological activity in the collecting system, thus any unusual intrarenal activity should be evaluated carefully. While increased bone tracer uptake in the irradiated region of the kidneys has been reported in the literature, altered biodistribution of FDG in irradiated renal tissue is not well described. We report a case of FDG PET/CT showing increased FDG activity in small portions of the kidneys that were previously irradiated.
