Results
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,
the ADC200-1500,
and D.

In each of the results from the linear regression of the estimated parameter maps calculated from the five b-value,
a significant correlation,
(R< ‒0.67),
was observed between ADC0‒200,
D,
and α,
and the measured shear stiffness.
In addition,
the relationship between the D and the measured shear stiffness had the best correlation for five b-value in this study (R=-0.8).

Moreover,
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.
