Abstract：Objective To explore the diagnostic efficacy of contrast enhanced ultrasound(CEUS)in breast lesions classified BI-RADS 4 by combined with BI-RADS classifying.Methods A total of 60 lesions classified BI-RADS 4 were ex-amined by CEUS before surgery.According to the pathological result, the efficacy of BI-RADS classifying, CEUS grade and combining both methods were evaluated.Results Of the 60 mammary lesions,34 benign lesions and 26 malignant lesions. The lesion of benign group and malignant group was statistically significant(P<0.05)in intensity,boundary,contrast agent distribution,filling defect and peripheral radial enhancement.The area ratio(AR),time-intensity curve(PT)was higher in malignant group than the benign group(t=4.20,t=3.31, P<0.05).The diagnostic compliance rate of ultrasonography score was 80.0%,and the diagnostic compliance rate of BI-RADS classification was 78.3%.The diagnostic compliance rate of the combined application was 90.0%,which was higher than that of separate use of either method.Conclusion The com-bine of CEUS and BI-RADS has higher diagnostic efficacy in untypical lesions than separate use of either method.
