Abstract:
Objective To study the influence factors of real-time shear wave elastography(SWE) on the elasticity of focal liver lesions (FLLs) measurement.Methods The mean Young's modulus of 160 FLLs were measured by SWE.The relation between elasticity with different aspects of FLLs were analyzed including postures (supine and left lateral position),respiratory phases (end of inspiratory and expiratory),the probe position (rib and intercostal space) and different operators.Results There were significant differences between different postures and respiratory phases in the elasticity measurement of FLLs by SWE (P ＜0.05).There was no significant difference between robe position and different operators in the elasticity measurement of FLLs by SWE(P ＞0.05).Conclusions The postures and respiratory phases can impact the elasticity measurement of FLLs by SWE.
