Any mass lesion on a background of a cirrhotic liver must be considered hepatocellular carcinoma until proven otherwise.

Shear wave elastography is an imaging technique that quantifies tissue stiffness by measuring the speed of shear waves in tissue. If the velocity in the liver is more than 1.99 m/s, this indicates cirrhosis.

The hepatic arterial resistive index is used for hepatic arterial evaluation, with the usual normal range between 0.55 and 0.8. The mean hepatic arterial peak systolic velocity (PSV) is 103 cm/s.

Recanalization of the paraumbilical vein is diagnostic of portal hypertension.
