  1. Pearson’s correlation method. This table summarizes the associations between the ASP, VTV, TLB, SUVmax, SUVmean, SUVpeak and PSA blood level using Pearson’s correlation method. Neither of the investigated associations presented a significant correlation (p > 0.05) to the ASP. Significant (p < 0.05) moderate correlations were demonstrated for VTV and TLB to SUVmax and as expected also to SUVmean and SUVpeak. PSA did not show a significant correlation (p > 0.05) to the investigated parameters. Abbreviations: ASP asphericity, VTV viable tumor volume, TLB total lesion binding rate, SUVmax maximum standardized uptake value, SUVmean mean standardized uptake value, SUVpeak peak standardized uptake value, PSA prostate-specific antigen blood level
