Abstract：Objective: To evaluate the usefulness of ultrasonic score in the diagnosis of benign and malignant breast diseases. Methods: 458 patients with 597 lesions were examined by ultrasonic elastography(UE) according to the five-point elastic score. All the cases received operations and pathological examinations. Result: 338 patients with 450 lesions were benign, and 120 patients with 147 lesions were malignant. The accuracy of UE score 1,2,3 for benign lesions is 97.5%, 96.7%, 85.7%, respectively; and the accuracy of UE score 4,5 for malignant lesions is 88.9%, 97.6%, respectively. Conclusion: UE is helpful for evaluating the tissue rigidity, but it should be consummated.
