Abstract:
ObjectiveTo explore the feasibility of detecting liver stiffness by virtual touch tissue quantification (VTQ) technique and establish a reference range of shear-wave velocity in healthy liver of adults.MethodsOne hundred and sixty-one healthy adults underwent VTQ detection to obtain the shearwave velocities of livers.Each subject received VTQ measurement in four parts of liver.Ten subjects were performed twice by two sonographers,respectively.Results① The liver shear-wave velocities of 161 healthy adults had a 95％ confidence interval from 1.089 to 1.105 m/s.Shear-wave speed values of intrahepatic different parts had no statistically significant.The ICC of measurement value of four parts in healthy liver was 0.80(95 ％ CI:0.75- 0.85).②The difference of shear-wave velocities in healthy livers in different age groups had no statistically significant,whereas the mean values in different gender had statistically significant (P =0.001).③No statistically significant was observed between the mean shear-wave velocity values obtained by different operators (P =0.82).ConclusionsThe liver shear-wave velocities of the healthy group have a reference range from 1.089 to 1.105 m/s.VTQ technique has a good reproduction and stability,therefore,using this technology to assess hepatic stiffness is noninvasive and feasible.
