Measurement of tumor volumes by contrast-enhanced CBCT scans. a Comparison of tumor volume calculation methods using Lx Hx W calculation in MuriSlice software or manual contouring in ImageJ software, respectively. b Pearson correlation analyses of tumor volumes as assessed by Lx Hx W method or contouring for irradiated and non-irradiated animals. c Comparison of tumor volumes as determined by contouring or Lx Hx W method. p-value as calculated by paired Wilcoxon-Rank test. d Differences in tumor volumes as determined by Lx Hx W method or contouring. p-value as calculated by exact Wilcoxon Rank test
