The results of this study are indicated in Figure 2 and 3.
The signal attenuation derived from the three b-values,
ADC0-1500 and D* against the measured shear stiffness,
showed good correlation in comparison to that from the use of five b-values.
In the fast diffusion component of three b-value,
D* resulted in good correlation while there was no correlation on the ADC0-200.
There was no correlation between the measured shear stiffness and the slow diffusion component,
In each of the results from the linear regression of the estimated parameter maps calculated from the five b-value,
a significant correlation,
was observed between ADC0‒200,
and the measured shear stiffness.
the relationship between the D and the measured shear stiffness had the best correlation for five b-value in this study (R=-0.8).

the comparison between conventional shear stiffness and virtual shear stiffness is shown in Figure 4 and 5,
demonstrating a correlation on each of the estimated parameters.
