Abstract: Objective To assess the value of contrast-enhanced ultrasonography (CEUS ) in diagnosing BI-RADS 4 breast lesion.Methods The CEUS findings of 79 breast lesions of BI-RADS 4 were analyzed,and the CEUS diagnosis was made according to our preliminary study results.Histology results were served as golden reference.Results Of all the 79 breast lesions that were confirmed by histopathology results,36 were malignant and 43 were benign.The differences of morphologic features of area variety, margin,heterogeneous or homogeneous distribution between benign and malignant lesions were significant (P < 0.05 ).The area under ROC curve of correction BI-RADS classification in the diagnosis of breast cancer was 0.938,and it was significantly higher than that of the BI-RADS classification (0.889,Z =2.209, P =0.0272).Conclusions CEUS can improve the diagnostic accuracy of breast lesions preoperatively.
