2.3.1. SUVmax of Malignant Lesions (P-P)

The Wilcoxon test showed a statistically significant difference in SUVmax between baseline and delayed scans. SUVmax was the highest in bone metastases (mean + standard deviation/SD: 17.0 ± 20.2 3 h p.i.; *p* < 0.001) and lowest in local recurrence in the prostate bed (10.1 ± 9.5 1 h p.i./11.7 ± 10.7 3 h p.i.; *p* < 0.001). The SUVmax of LNM showed high values of 15.2 ± 15.5 3 h p.i. for pelvic LNM (*p* < 0.001) and 15.6 ± 15.6 3 h p.i. for extra-pelvic LNM (*p* < 0.005) (Table 3, Figure 2).
