SUVpeak and SUVmax as a function of 18F-FDG uptake time. Original SUVpeak [(A); (B), left panel] and SUVmax [(C); (D), left panel] and uptake time-adjusted (ti = 60 min) SUVpeak′ [(B), right panel] and SUVmax′ [(D), right panel). Circles indicate values from prone PET (P); adjoining circles indicate values from supine PET (S). Squares represent example subjects illustrated in Fig. 7. ****P < < 0.0001, Bonferroni-corrected Wilcoxon signed rank test.
