Two-dimensional shear wave elastography of the liver

Two-dimensional shear wave elastography in a patient with healthy liver parenchyma (A) and a patient with liver cirrhosis (B). The color indicates the stiffness of the liver: blue means soft, and red means hard. At least one box can be drawn within the area being evaluated; the value of the shear wave speed is shown on the right side of the image either in m/s (top) or in kPa (bottom).
