Abstract:
Objective To investigate the application value of improved intermittent compression strain elastography in im-proving the image stability of breast elastography and the identification ability of benign and malignant nodules.Methods In all,113 patients(138 breast lesions)were recruited in this study,who accepted high frequency color Doppler ultrasound,im-proved intermittent compression strain elastography(IICSE)and nonintermittent compression strain elastography(NCSE)one week ahead of the surgery.By comparing the first three times of IICSE and NCSE,the same elastic result rate was obtained,and the receiver operating characteristic(ROC)curve of IICSE and NCSE elastic score was drawn to identify benign and malignant breast lesions,and the area under the curve(AUC)was calculated,and those with larger AUC area were selected to adjust the classification of BI-RADS.To compare the difference of diagnosis of benign and malignant breast lesions of different BI-RADS classification by high-frequency color ultrasound and high-frequency color ultrasound combined with IICSE,and the difference of the composition ratio of nodules classified by different BI-RADS.Results The consistency rate of elastic results obtained by IICSE was higher than that of NCSE(90.6％vs.34.8％,P＜0.05).ROC curve showed that the area under the curve(AUC)of IICSE was greater than that of NCSE(0.865 vs.0.636,P＜0.05).Comparing the results before and after high-frequency color ultrasound combined with IICSE,the number of BI-RADS type 3 and type 5 nodules increased significantly,while the number of BI-RADS type 4 nodules decreased(both P＜0.05).Conclusion IICSE improves low stability of conventional elastic ima-ging.At the same time,IICSE reduces the number of patients who need further examination,reducing overuse of medical re-sources.
