Abstract: Objective To investigate the value of ultrasonic elastography(UE) in diagnosing breast small masses (diameter≤10 mm). Methods The static sonograms of conventional ultrasound(US) and UE of the 274 breast small lesions which pathologically proved were reviewed. Images were assigned according to the B1-RADS criteria for US. The elastographic images were evaluated using improved 5-scoring system.Pathology was followed up as diagnostic criteria. The diagnostic performance of the 2 methods was evaluated with receiver operating characteristic curve(ROC). Results The areas under the ROC curve of the two modalities were 0. 891 (UE) and 0.742 (BI-RADS), respectively. The difference between them was significant. Conclusions UE is helpful in differentiating between malignant and benign breast small lesions.
