Image quality parameters of the NEMA PET body phantom filled with 18F-FDG, 68Ga-HCl, or 64Cu-HCl. Semiquantitative image quality specified as the mean, maximum and peak recovery coefficient (RCmean, RCmax, and RCpeak, respectively), percent contrast between each sphere and the background (contrast recovery coefficient (CRC)) and contrast–noise ratio (CNR) for each of the six spheres of the NEMA PET body phantom filled with 18F-FDG, 68Ga-HCl, or 64Cu-HCl at a sphere-to-background activity concentration ratio of approximately 4:1 without the simulation of an obese patient (normal weight setup)
