A 55-year-old female patient with an invasive non-special type breast cancer. Two-dimensional grayscale image of breast cancer showing posterior echo attenuation and rich blood flow signal inside the breast cancer (a). The probe was kept stable still before elastic imaging scanning, when the ROI area was almost all green, the image stability was good, and the elastic modulus value of the mass was measured with STE (b). E images showed that the mass was hard with a “stiff-rim” sign, the elastic modulus value of the nodule was measured by E imaging, and Emax was 133 kPa (c). The pathology results confirmed that the lesion was an invasive non-special type carcinoma (HE, 100 ×) (d)
