Comparisons of tumour-to-background ratios (TBRs). a There were significant differences between TBRs of dbPET and whole-body PET/CT in both peripheral (12.38 ± 6.41 vs 6.73 ± 3.5, p = 0.0006) and non-peripheral (12.44 ± 5.94 vs 7.71 ± 7.1, p = 0.0183) groups. b There was no significant difference in the TBR of dbPET between the peripheral and non-peripheral groups (p = 0.8261)
