Figure 1: Acoustic radiation force impulses principle: Transducer generates ultrasound push pulses into the liver (thick arrow) which results in shear waves as it travels through the tissue. Region of interest box placed at a given depth can detect the shear wave as shown, converted into velocity and is a function of the elasticity of the tissue which is indicative of the stiffness of the parenchyma
