Figure 3: Images in a 62-year-old woman with invasive ductal carcinoma.

(a) The lesion (arrows) is shown on B-mode ultrasound. (b) The lesion (arrows) shows irregularly distorted and chaotic contour lines on the shear wave propagation mode. (c) The Emean, ESD and Eratio of the lesion (arrows) on elasticity mode are 42.8 kPa, 38.5 kPa and 4.98 respectively. (d) The Emean, ESD and Eratio of the lesion (arrows) on shear wave speed mode are 3.40 m/s, 2.10 m/s and 2.00 respectively.
