*2.3. SUVmax*

An increase of tracer accumulation over time was observed in patient groups P-P, P-I, and P-T. The SUVmax values of the detected sites of PCa lesions of the late scans were higher than those of the baseline scans. Overall, the SUVmax values of tumor lesions in the late PET/CT scans was higher in 22.1% (P-P), 22.5% (P-I), and 17.8% (P-T) than the SUVmax values in the baseline scans (each *p* < 0.001) (Table 3).
