Abstract
Objective To compare the application value of shear wave elastic imaging (SWE) and strain elastography imaging in differential diagnosis of benign and malignant breast masses.Methods The study included 90 cases of breast masses found by ultrasound examination in the Affiliated Hospital of Binzhou Medical Universityfrom July to December 2017, there were 92 breast masses.SWE technology and strain elastography technology were performed before surgery.The Emaxvalue of 92 breast masses was measured by SWE, and the diagnostic threshold of Emaxvalue was obtained for diagnosis.After, strain elastography was used and the diagnosis was made by 5 points.Histopathologic result after surgery was adopted as diagnostic reference.Compared with pathological results, the sensitivity, specificity and accuracy of SWE and strain elastography technology were calculated.ResultsThe optimal cut-off value was 61.45 kPa to distinguish malignant breast solid lesions from benign for SWE.Generally, the sensitivity, specificity and accuracy were 84.85％, 94.92％ and 91.30％for SWE, and 87.88％, 86.44％ and 86.96％for strain elastography, respectively.The difference in diagnosis efficiency among SWE and strain elastography in differential diagnosis of benign and malignant breast tumors was statistically significant (P<0.05).Conclusion SWE and strain elastography are all useful for the differential diagnosis of benign and malignant breast tumors.But the diagnosis efficiency of SWE is superior to strain elastography.Each approach has respective advantages, it should be used flexible.关键词
