Invasive and non-invasive diagnosis of cirrhosis and portal hypertension

Figure 2 Doppler ultrasonography showing change in the hepatic vein waveform and damping index (A) before and (B) 3 mo after propranolol treatment in a patient with liver cirrhosis. Hepatic vein waveform changed from biphasic to near triphasic, quantitative measurement of damping index (DI) decreased from 0.61 to 0.33 in association with a hepatic venous pressure gradient (HVPG) decrease from 18 to 11 mmHg[92]. HVPG: Hepatic venous pressure gradient.
