  1. ACC activity concentration, BSA body surface area, BW body weight, HU Hounsfield unit, LAC linear attenuation coefficient, LBW lean body weight, r, Pearson's correlation coefficient, SUV, standardised uptake value. *Correlation significance for LAC vs. ACC (kBq/ml) was p < 0.001. All the other correlations were p < 0.0001.
