Figure 3
Inter-tumour variability in MRI parameters. Absolute coefficients of variation (CV) of mean, median, SD, kurtosis and skewness parameter values across 39 HCC tumours (in 32 patients). Kurtosis and skewness showed a substantially higher inter-tumour variability compared to mean and median values. ADC = apparent diffusion coefficient, ART = arterial fraction, DV = distribution volume, Fa = arterial flow, Fp = portal flow, Ft = total flow, MTT = mean transit time, R1 = longitudinal relaxation rate, R2* = transverse relaxation rate.
