| Parameter | Non-csPCa | csPCa | P |
| SUVmax of prostate lesion | 4.63 (2.90–9.87) | 10.15 (5.45–30.95) | <0.001* |
| SUVmax for… | |||
| Liver background | 5.47 (3.05–9.74) | 5.42 (4.62–8.60) | 0.484 |
| Prostate background | 3.3 (2.00–4.40) | 3.5 (2.70–4.20) | 0.130 |
| Prostate lesions vs. prostate background | 1.43 (1.12–4.94) | 3.36 (1.44–10.32) | <0.001* |
| Prostate lesions vs. liver background | 0.91 (0.64–2.12) | 1.48 (1.03–6.03) | <0.001* |
↵* Significant differences (P < 0.05).
csPCa has GS ≥ 7; non-csPCa has GS of 6 or is normal prostate or benign prostatic disease. Data are median followed by range in parentheses. P values are for Wilcoxon–Mann–Whitney U test.
