Abstract: Objective To compare the value of shear wave elastography (SWE)and mammography in differential diagnosis of benign and malignant breast neoplasms.Methods Totally 96 patients with breast tumor were randomly chosen and underwent SWE andmammography.The elastic maximum value (Emax)was obtained. Taking histological diagnosis as the golden standards,we compared the two techniques' sensitivity,specificity, accuracy,positive and negative predictive value in diagnosis of breast tumors.Results The sensitivity,specificity, accuracy,positive and negative predictive value of Emax were 91.3%,94.0%,92.7%,93.3% and 92.1%, respectively.The sensitivity and accuracy of E-max were significantly better than those of x-ray (both P <0.05 ). The area under the ROC curve of Emax was 0.983 (95% CI,0.963 to 0.998).Conclusion SWE outperforms mammography in differential diagnosis of benign and malignant breast tumors.
