Quantitative results of the prospective study. a is the Bland–Altman plots of the liver, the blood pool and the muscle SUVmean between DPR_1/3(p) images and the reference. b, c are the comparisons of the lesion SUVmax and TLR between DPR groups and the reference (blue line: an increase; orange line: a decrease). The SUVmax and TLR of all the DPR groups were significantly improved compared to the reference group. d–f are the comparisons of the liver, the blood pool and the muscle COV between DPR groups and the reference. The liver, the blood pool and the muscle COV showed no significant difference between the DPR_1/3 group and the reference. ****p < 0.0001; ns, no significant difference. SUV, standardized uptake value. TLR, tumor-to-liver ratio. COV, coefficient of variance
