Results
SWV was higher in the metastasis group with significant difference (P<0.01).
The average and median ADC values were lower in the metastasis group with significant difference (p=0.024 and 0.036,
respectively; Table 1,
Figure 3).
To note,
the significance of the difference was stronger in SWV compared to ADC (average,
median).
On the other hand,
the difference in SD of ADC was not significant between the groups (Table 1,
Figure 4).
The correlations were not significant between SWV and the average or median of ADC in all of control,
metastasis,
and total subjects groups (Table 2,
Figure 3).
To the contrary,
the correlation between SWV and SD of ADC was significant regardless of the existence of metastasis (Table 2,
Figure 4).
Table 1: Comparison between control and metastasis groups.
Data indicate the average of the acquired parameters from the control and metastasis groups and their comparison between the groups; standard deviations are in parentheses. ADC: apparent diffusion coefficient, SWV: shear wave velocity. SD: standard deviation.

Table 2: Correlations between SWV and ADC parameters.
Data indicate the average of the acquired parameters, with standard deviations in parentheses; coefficients of correlation between the parameters of SWV and ADC are also shown. ADC: apparent diffusion coefficient, SWV: shear wave velocity, SD: standard deviation.
