Abstract Objective: To compare the value of the modified ultrasound elastography score and the ultrasound elastic strain ratio in the differential diagnosis of four types of breast benign and malignant lesions in breast imaging reporting and data system for ultrasound (BI-RADS). Methods: A total of 83 cases of breast lesions (96 breast masses) in our hospital were selected, who were graded by modified ultrasound elastography, and the elastic strain ratio of ultrasound was measured. According to the results of operation and pathology, and by plotting the receiver operating characteristic (ROC) curve of the subjects, the diagnostic efficacy of the modified ultrasound elastography and strain ratio in the differential diagnosis of BI-RADS 4 types of breast benign and malignant lesions was evaluated. Results: Among the 96 breast masses, 41 of 4A, 32 of 4B and 23 of 4C were diagnosed by ultrasonography before operation, 56 of them were malignant and 40 of them were benign. The sensitivity, specificity, accuracy and yoden index of the two methods were 69.64% (39 / 56), 73.21% (41 / 56), 72.50% (29 / 40), 82.50% (33 / 40) and 70.83% (68 / 96), 77.08% (74 / 96) respectively. The ROC curve analysis showed that the area under the ROC curve was 0.86, which was higher than that of the modified elastography (0.74). Conclusion: The modified elasto-sonography score and the elastic-strain ratio of ultrasound have important guiding value in the differentiation of four types of breast benign and malignant lesions in BI-RADS, but the elastic-strain ratio of ultrasound may be more reliable and objective, which has a good diagnostic value in the differentiation of four types of breast benign and malignant lesions in BI-RADS.
