- Abstract
Objective: To observe the typical performance of shear wave elastography (SWE) in benign and malignant breast lesions, and to explore the value of SWE in differential diagnosis of benign and malignant breast lesions. Method: 162 patients with breast masses who underwent SWE examination in our hospital from June 2017 to June 2019 were selected. 105 cases of benign masses (benign group) and 57 cases of malignant masses (malignant group) were confirmed by biopsy or pathology. The differences of SWE typical performance, SWE parameters [Emax, Emin, Emean, standard deviation (SD), SWE-Ratio] between benign and malignant breast lesions were compared, and the value of SWE in differentiating benign and malignant breast lesions was analyzed. Result: The detection rate of "stiff rim sign", elastic image of type III-type V, Emax, Emean, SD and SWE-Ratio of breast masses in malignant group were higher than those in benign group (P<0.05), and Emin was lower than that in benign group (P<0.05). Logistic regression analysis showed that "stiff rim sign", Emax, Emean and SWE-Ratio were independently correlated with the pathological diagnosis of breast mass (P<0.05). The results of receiver operator characteristics curve (ROC) curve analysis show that the area under curve (AUC) of "stiff rim sign", Emax, Emean and SWE-Ratio in diagnosing benign and malignant breast lesions were 0.923, 0.686, 0.873 and 0.879, respectively. Conclusion: SWE is an effective imaging method in the diagnosis of benign and malignant breast lesions. SWE "stiff rim sign", SWE-Ratio and Emean have high value in differentiating benign and malignant breast lesions.
