a MIP FDG PET image of patient 39 with a small lung tumor in the right upper lobe with a low FDG activity (SUVmax 1.5) and TLG2.5 < 50 ml*SUV. b Axial slice of the tumor in the right upper lobe. c Histogram of the VOI illustrated in d-f (green box), with the threshold lines for TLG42% (green) and the cut off for BSL (red). BSL is represented by the sum of all yellow voxels in the histogram. d illustrates the volume covered by all voxels with a SUV above 42% of SUVmax representing TLG42% (9.9 ml*SUV). e TLG2.5 fails to measure any tumor activity (TLG2.5 0 ml*SUV) and f represents the activity of all voxels above background (BSL 15.2 ml*SUV), overestimating the reference activity for this lesion (TLGRC 13.3 ml*SUV) only by 14%.
