Normal values of shear wave velocity in liver tissue of healthy children measured using the latest acoustic radiation force impulse technology

Figure 1 Virtual touch imaging quantification measurements in the right liver lobe of a 3-year-old boy at depths of 1. 5 cm, 2.0 cm, 2.5 cm, 3.0 cm from the skin surface, respectively, with a superior quality of the elastic image.

Figure 2 Virtual touch imaging quantification measurements in the left liver lobe of a 10-year-old girl at depths of 1. 5 cm, 2.0 cm, 2.5 cm, and 3.0 cm from skin surface, respectively, with a good quality of the elastic image.

Figure 3 Box-and-whisker plot of the shear wave velocity value of the virtual touch imaging quantification measurement in each liver lobe at different measurement depths. Significant differences were found between any two measurement depths. Statistically significant by the Kruskal-Wallis test with Bonferroni’s adjustment. ^aP < 0.05.
