Rational arrangement of measuring shear wave speed in the liver

Figure 1 Distribution of robust coefficient-of-variation among the cases. A: As shown in the upper panel, the lowest coefficient-of-variation (CVR) that covers 95% of cases was 42.1% (black dotted line) and 40.4% (gray dotted line) in right posterior (black line) and anterior segments (gray line), respectively, while the lower panel shows that 60.4% (black dotted line) and 52.8% (gray dotted line) of the CVR are required in the left medial (black line) and lateral (gray dotted line) segments, respectively. B: The cumulative distribution of the CVR was significantly different between the right (continuous line) and left (dotted line) lobes (upper panel, ^aP < 0.0001), and there is still a significant difference when the subjects are restricted to cases in which the CVR was 40.4% or less in any segment or lobe (lower panel, ^bP < 0.0001).
