Comparison of the lesion TBR between GS and DLR groups. Left: The HYPER DLR algorithm can improve the lesion contrast significantly compared to that achieved by GS approach with the same acquisition duration. Right: Compared with the reference GS_180 group, the DLR_135 group shows no significant difference in TBR, indicating a similar lesion contrast. **p < 0.01; ***p < 0.001; ns, no significant difference.
