Abstract
Objective: To establish the reference value of liver virtual touch tissues quantification (VTQ) values in healthy subjects. Methods: Liver stiffness was measured with Siemens Acuson S2000 ultrasound system in totally 300 healthy subjects. The first one hundred healthy subjects received VTQ measurements in four parts (superficial and deep parts of right lobe, superficial and deep parts of left lobe). Then the achievement rate in different part of liver was calculated to choose the suitable measuring position. On the other hand, the reproducibility was analyzed with intraclass correlation coefficient (ICC). The last two hundred healthy subjects received VTQ measurements in the suitable position only. The reference value of VTQ was calculated using x̄±1.96s. Results: It was stable to measure liver stiffness with VTQ technique. The achievement rate was high in right lobe, and the deep parts of right lobe was the best measuring position. There was significant difference of VTQ value between males and females (P
