Objective To explore the application value of using the acoustic guide cushion to improve the stability of the shear wave elasticity measurement.Methods A total of 147 lesions in 147 patients (91 benign and 56 malignant) were collected to compare the consistency within the operator and the consistency with the pathological diagnosis.Results In all breast lesions, the elastic values (Emax, mean, Esd) in the coupling and acoustic guide groups were higher than the benign lesions (P <0.001).The consistency of Emax, Emean and Esd was very good (ICC values> 0.75) and Emin (ICC value =0.613).The agreement of Emax, Emean, Emin, and Esd was good in the coupling agent group (0.4
