Abstract Objective To research the clinical diagnostic value of high frequency ultrasound combined with BI-RADS grading in breast tumors. Methods From February 2015 to August 2017, the clinical records of 128 patients with breast tumors (159 lesions) in Huzhou Central Hospital were analyzed, retrospectively. The bilateral breasts were scanned with high frequency ultrasound, and the breast lesions were evaluated according to BI-RADS. The BI-RADS classification and pathological results were compared and analyzed. The clinical value of high frequency ultrasound combined with BI-RADS classification in the diagnosis of breast tumors was evaluated. Results Among 159 breast tumor lesions, 98 benign lesions were confirmed by pathological findings, and 61 malignant lesions were confirmed by pathological findings. The detection rate of malignant lesions in irregular shape, incomplete capsule, marginal burr, internal calcification and axillary lymph node abnormalities were significantly higher than those in benign lesions, the differences were statistically significant (P < 0.01). The internal blood flow of malignant lesions was more abundant than benign lesions. The level of Vmax and RI value of malignant lesions were significantly higher than those of benign lesions, and the differences were statistically significant (P < 0.01). A total of 85 lesions were diagnosed as grade 3 by the BI-RADS classification, which 7 lesions were malignant. There were 35 lesions were diagnosed as grade 4, which 17 lesions were malignant. 39 lesions were diagnosed as grade 5, which 37 lesions were malignant. The sensitivity of BI-RADS classification ultrasound was 88.52% (54/61), the specificity was 79.59% (78/98), and the accuracy was 83.02% (132/159). Conclusion BI-RADS classification has high sensitivity and specificity in the diagnosis of breast tumors. The combination of high frequency ultrasound and BI-RADS classification have great significance for the diagnosis and characterization of breast tumor and the guidance of the treatment scheme.
