Box plots for comparison of objective image quality parameters in tumor lesions among the different PET acquisition groups in terms of patient-based (A–C) and lesion-based (D–F) analysis. As a general trend, SUVmean decreased while moving from longer to shorter-duration protocols, although the changes with the reference 10-min values were non-significant up to 5-min acquisitions (A, C). SUVmax was significantly lower in PET-10 than all other shorter-duration protocols (B, D). TBR decreased in shorter protocols, although the decrease was non-significant up to 8-min and 6-min acquisitions in patient- and lesion-based analysis respectively (C, F)
