This is a prospective longitudinal study that will evaluate if changes (pre and post therapy)
in indocyanine green (ICG) retention test and liver stiff ness (LS) and spleen stiffness (SS)
as measured by acoustic radiofrequency impulse (ARFI) correlate with changes in portal
pressure as determined by the hepatic vein pressure gradient (HVPG) in patients with
compensated hepatitis C virus (HCV) cirrhosis undergoing antiviral therapy.
