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.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
