Box plots demonstrated the inter-group differences in ASL-derived parameters between the PR and SD groups, as well as between the residual and the non-residual groups. The horizontal line denotes the median values of the parameters (the 50th percentile). The top and bottom of the box denote the 25th and the 75th percentile, respectively. As can be observed from the box plots, Pre-TBF and ΔTBF can distinguish between the PR and the SD group, as well as between the residual and the non-residual group (a, c, d, and f), whereas the Post-TBF of the residual group showed an overlap with the non-residual group (b and e). Pre-TBF: pre-treatment tumor blood flow; Post-TBF: post-treatment tumor blood flow; ΔTBF: changes in tumor blood flow; PR: the partial response group; SD: the stable disease group; R: the residual group; NR: the non-residual group
