导声垫在提高乳腺病变剪切波弹性成像测值稳定性的应用价值

目的 通过比较加用导声垫前后剪切波弹性成像测值的差异,探讨使用导声垫对提高剪切波弹性测值稳定性的应用价值。方法 收集147例患者共147个病灶(良性91例,恶性56例),由同一操作者不同时间分别借助耦合剂和导声垫对乳腺病灶进行三次剪切波弹性成像测量,比较测值操作者内一致性和与病理诊断的一致性。结果 在所有乳腺病灶中,耦合剂组与导声垫组恶性病灶各弹性测值(Emax、Emean、Esd)均较良性病灶高(P＜0.001)。导声垫组Emax、Emean、Esd重复性测量的一致性非常好(ICC值均>0.75)、Emin的一致性好(ICC值=0.613)。耦合剂组Emax、Emean、Emin、Esd的一致性好(0.4

The application value of acoustic guide pad in improving the stability of shear wave elastography in breast lesions

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
