Figure 1

Fused positron emission tomography and magnet resonance image (PET/MRI). (a) A delineated volume of interest (VOI) of the total kidneys is schematically indicated in blue. (b) FDG time activity curves in units of standardized uptake value (SUV). The curves show the average over all 13 measured transplant kidneys (bold blue line) ± one standard deviation (thin blue lines), and for comparison the average over 48 healthy kidneys (bold purple line) ± one standard deviation (thin purple lines). The general kidney performance (GKP) represents the FDG uptake between minute 2 and 3.
