Bland–Altman plots illustrating the relationship between histology index tumor volume (HTV) in comparison to the volumes estimated on magnetic resonance (MR) imaging after correlation with whole mount pathology (WMP; left column) and surgical pathology report (SPR; right column), for the individual MR parameters. The blue horizontal line corresponds to the mean difference, dashed red lines show 1.96 standard deviation (SD) interval. In all cases, there was a tendency for the imaging-based approaches to underestimate HTV. ADC, apparent diffusion coefficient; DCE, dynamic contrast enhanced; MRTV, magnetic resonance tumor volumes; T2W, T2-weighted imaging.
