Correlations between tumour-to-blood uptake ratios and the trapping rate are enhanced when uptake is corrected for the distribution volume. Left side: tumour-to-blood uptake ratio of FAZA versus trapping rate; right: tumour-to-blood uptake ratio corrected for the distribution volume versus trapping rate. a and b voxel-scale values for a representative patient tumour (pt. 2) using TAC 1. c and d same as a and b but with TAC 2. e and f Tumour-scale values using TAC 2 for all 20 tumours. Pearson correlation coefficients are shown
