Abstract Objective: To assess the combination of superb micro-vascular imaging(SMI) and BI-RADS-US classification in the diagnosis of breast cancer. Methods: This study included 136 patients with 174 breast tumors, all patients enrolled in the joint application of SMI and BI-RADS-US classification examination for diagnosis confirmed by pathology finally. Results: The Alder scale from 0～Ⅲ accounted for benign and malignant tumors by SMI were 88.78%(87/98), 8.16%(8/98), 2.04%(2/98), 1.02%(1/98) and 1.32%(1/76), 9.21%(7/76), 61.84%(47/76), 27.63%(21/76), respectively. The difference between the two groups was statistically significant(P<0.05)． The sensitivity, specificity, accuracy of BI-RADS-US alone and SMI with BI-RADS-US was 77.63%, 83.67%, 61.30% and 94.74%, 91.84%, 86.58%. The combination of SMI and BI-RADS-US was superior to BI-RADS-US alone, the difference between the two groups was statistically significant(P<0.05). Conclusion: The combination of SMI and BI-RADS-US is more effective method for evaluating the diagnostic value of breast cancer than BI-RADS-US alone, having comparatively higher value for clinical application．
