Table 2 Overview of the measured parameters with VTTQ (Virtual Touch Tissue Quantification), VTIQ (Virtual Touch Tissue Imaging & Quantification) and ASQ (Acoustic Structure Quantification). Wilcoxon-Mann–Whitney-test was used to differentiate the groups. The level of significance was set to α = 0.05
