SWE diagnosis of patients with breast nodules. (a) Emax of different pathologies (invasive breast cancer, fibroadenoma, adenosis and intraductal papilloma). The Emax of invasive breast cancer was higher than that of fibroadenomas, adenoses and intraductal papillomas, but it had no statistical significance with intraductal papillomas (p = 0.100). (b) The Emax of malignant breast nodules was significantly higher than that of benign breast nodules. (c) The Emean of malignant breast nodules was significantly higher than that of benign breast nodules. (d) ROC curve for Emax in diagnosing benign and malignant lesions. (e) ROC curve for Emean in diagnosing benign and malignant lesions. Values are means ± SD. Comparisons between two groups were made using Student’s t-test. Differences between more than two groups were compared using one-way ANOVA. *p < 0.05, **p < 0.01. Emax, Maximum elasticity; Emean, Mean elasticity; ROC, Receiver operating characteristic; SD, Standard deviation; SWE, shear wave elastography; ANOVA, analysis of variance.
