Abstract：Objective To explore the diagnostic value of of Breast Imaging Reporting and Data System-Ultrasound( BI-RADS) lexi-con for category 3-5 breast lesions.Methods A retrospective analysis of the performance of 65 breast cancer and 92 benign breast lesions with ultrasound, comparing The BI-RADS-US lexicon including Irregular shape, non-circumscribed margin, non-parallel orientation, micro calcification, shadowing, echogenic halo, lesions internal flow and RI≥0.7,comparison of the sensitivity, specificity and accuracy. Results Irregular shape, non-circumscribed margin, non-parallel orientation, micro calcification, shadowing, echogenic halo, lesions internal flow and RI≥0.7 were more frequently found in malignant lesions than in benign lesions.A good sensitivity was demonstrated (93.7%) when using the non-circumscribed margin as a criterion for malignancy, and high specificity was achieved when other descrip-tors including Irregular shape, non-parallel orientation, micro calcification, shadowing, echogenic halo, lesions internal flow and RI≥0.7 were used as differentiation criteria, especially micro calcification and echogenic halo, the specificity was 95.5%, 96.8%.Conclusion Non-circumscribed margin are proved as the most valuable sign for screening malignant breast lesions.High specificity was found for Irreg-ular shape, non-parallel orientation, micro calcification, shadowing, echogenic halo, lesions internal flow and RI≥0.7, which can help biopsy and preoperative diagnosis.When breast lesion occurs one of the above BI-RADS-US lexicon tend to BI-RADS category 4B le-sions, micro calcification, echogenic halo or two of the remaining BI-RADS-US lexicon, should be BI-RADS category 4C lesions, three or more BI -RADS category 5 lesions.
