(a) In vivo liver shear moduli estimates in twenty human volunteers using an intercostal imaging approach between the ninth and tenth ribs. (b) Comparison of reconstructed in vivo liver shear moduli in two human volunteers over a four month period. Six measurements were performed intercostally on each day in each volunteer between the ninth and tenth ribs. In both (a) and (b), the reconstructed shear moduli represent the mean and standard deviation over six independent measurements, where values that didn’t meet the goodness of fit parameters (R² > 0.8, 95% CI < 0.2) or were greater than one standard deviation from the mean for a given measurement were excluded from the analysis. (c) Mean reconstructed shear moduli in the 20 volunteers as a function of their BMI. The left vertical dashed line represents the distinction between normal and overweight volunteers, while the right vertical dashed line represents the distinction between overweight and obese volunteers.
