ObjectiveTo explore the clinical value of ultrasound elastography（UE）combined with super microvascular imaging（SMI） in correcting BI-RADS grade.Methods Retrospecting 86 BI-RADS 3～5 grade breast masses classified by conventional ultrasonography

and these BI-RADS grades were corrected by UE combined with SMI.Receiver operating characteristic（ROC）curve was created by setting the pathological results as gold standard

the sensitivity

specificity

accuracy and the area under curve（AUC）of the BI-RADS grades in differentiating benign and malignant breast masses before and after the correction were compared.Results BI-RADS 4 B grade was taken as the diagnostic cut-off point

after being corrected by UE combined with SMI

the sensitivity

specificity

accuracy and AUC were 95.65%

90.00%

93.02% and 0.954

respectively

all higher than those before the correction（80.43%

67.50%

74.42% and 0.853）

the differences were statistically significant（all P<0.05）.ConclusionThe combination of UE and SMI can improve the effect in differentially diagnosing benign and malignant breast masses by correcting BI-RADS grade.
