Figure 1.
The image of a Vi.PLUS measurement, which was performed in a NAFLD patient. The viscosity is displayed in the left part of the image. Colors close to yellow white are indicative of high viscosity, while red means low viscosity. Numeric Vi.PLUS results (expressed in Pa.S) are shown on the left side of the image. NAFLD, non-alcoholic fatty liver disease; SD, standard deviation; SI, stability index; Vi.PLUS, Viscosity plane-wave ultrasound.
