The value of shear wave average velocity in healthy’s liver by using acoustic radiation force impulse imaging

SUMMARY:

Objectives: The purposes of this study were to measure the reference value of average velocity of shear wave in healthy’s liver by using acoustic radiation force impulse imaging.

Methods: Two hundred and of healthy volunteers with normal liver function test values were selected for the study. Shear wave velocity measurements, expressed in meters per second, were taken in liver segment 7 or 8 at depth from 3 to 4cm below the body surface portion of. Among these volunteers, we chose fifty ones to whom two observers with different levels of experience performed the measurements independently and blindly.

Results: Total the measurements are taken 2.532 times. The value of average velocity of shear wave in the health’s liver is 1.05 ± 0.12m/s. There is no statistically significant difference in shear wave velocity between two genders. In term of interobserver results, there is no statistically significant difference in shear wave velocity obtained by two observers with different levels of experiences (P < .005).

Conclusions: The results of this study show that shear wave velocity measurement in health’s liver by using the acoustic radiation force impulse technique is about 1.05 ± 0.12m/s and this technique is reproducible and independent to user.
