Abstract:
Objective To assess the applicability of sound touch elastography ( ST E) and sound touch quantify ( ST Q ) in measuring liver and spleen stiffness . Methods One hundred and eighteen healthy volunteers were included and underwent ST E and ST Q . T he success rate ,variability and reproducibility of ST E and ST Q were analyzed . T he accurate sampling size and number of tests for liver ST Q were also analyzed . Results T he success rates ,variability ,reproducibility of ST E and ST Q in liver were 97 .5% and 99 .2% ,8 .7% and 12 .0% ,0 .917 and 0 .916 , respectively . While those with spleen were 76 .3% and 66 .9% ,12 .4% and 16 .4% ,0 .847 and 0 .706 ,respectively . The sampling size of 1 .5 cm×1 .0 cm yield the lowest variability ( 8 .5% ) ( F ＝6 .562 , P ＝0 .002) ,and there was no significant difference between results of detecting 5 times and 10 times( P ＝0 .571) . T he liver and spleen stiffness of ST E were 5 .75 kPa ( 95%CI :5 .60－5 .91 kPa) and 15 .58 kPa ( 95% CI :14 .99 －16 .16 kPa) . Conclusions The measurement of liver stiffness using both ST E and ST Q have a high success rate and low variability . However ,ST E is better than STQ in measuring spleen stiffness .
