Bland-Altman plots demonstrating intra- and inter-observer (modest) agreement of tumour volume quantification in 10 patients: a average mean difference of − 0.27 cm3 and limits of agreement from − 7.93 cm3 (− 28%) to 8.47 cm3 (31%) for intra-observer variability; and b average mean difference − 2.5 cm3 and limits of agreement − 7.65 cm3 (− 28%) to 12.59 cm3 (46%) for inter-observer variability. Figures were created using Stata software, version 14
