This article is an open access publication Abstract performance of SD using DICOM or JPG estimations was Purpose Shear wave elastography (SWE) visualises the lower than the manual or QDE estimation (AUC 0.673 vs. elasticity of tissue. As malignant tissue is generally stiffer 0.844). than benign tissue, SWE is helpful to diagnose solid breast Conclusions The algorithm introduced in this study is suit- lesions.
