Comparison of the tumour/background ratios (TBRs) from 2 to 10 min between 18FDG-foci evidenced (+) or not (−) in 3D-OSEM-reconstructed (a) and PSFallpass-reconstructed (b) head-and-neck PET data sets. The comparison was not performed at 8 min for PSFallpass-reconstructed images because of the number of values in the PSF− group (n = 2)
