Figure 4.
Breast MRE images from exams performed on patients with a fibroadenoma (top row) and an invasive carcinoma (bottom row). The acquisitions were performed using 65-Hz vibrations applied to the lateral side of the breast. MR magnitude images from the MRE acquisition are shown in the first column, while shear stiffness and viscosity images from the MRE reconstruction are shown in the second and third columns, respectively.
