Acoustic Radiation Force Impulse (ARFI) technique in ultrasound with Virtual Touch tissue quantification of the upper abdomen Tecnica Acoustic Radiation Force Impulse (ARFI) nello studio ecografico con Virtual Touch tissue quantification dell'addome superiore

Purpose. Virtual Touch tissue quantification is an implementation of ultrasound (US) Acoustic Radiation Force Impulse (ARFI) imaging that provides numerical measurements (wave-velocity values) of tissue stiffness. The aim of this study was to define the normal values of shear-wave speed for the healthy liver, gallbladder, pancreas, spleen and kidneys. Materials and methods. Thirty-five young healthy
