Table 3 Top: Correlation matrix of Pearson correlation coefficients between the mean voxel-scale parameters across the twenty tumours studied using the 2-h data sets. Bottom: Population-averages of the corresponding voxel-scale rate coefficients; values are shown in units of h −1. Standard deviations of mean values across patients are indicated in parentheses. Also shown is the population average k eq value, which was calculated from fits to data from all voxels in each tumour, as described in the text
