Overview
On ultrasonography, changes in liver contours and nodularity may be evident. The echo texture may appear coarsened along with increase in echogenecity from focal fatty changes and irregular appearing areas. It can also be used to screen for hepatocellular carcinoma, portal hypertension and Budd-Chiari syndrome.
Echocardiography
Echocardiogram may be helpful in measuring the ejection fraction, and ischemic and hypokinetic areas of the ventricles in establishing diagnosis of congestive cardiac failure as a cause of liver cirrhosis.
Ultrasound
Following changes may be noted:
- Changes in liver contour
- Nodularity
- Increase in echogenecity from focal fatty infiltration
- Vascular changes:
- Flow across both portal and systemic circulation increases
- Resistive Index increases in end stage liver disease
- Vessels appear elongated and tortuous, called "corkscrewing" of the vessels
- Doppler ultrasound may show spontaneous shunts
- Splenomegaly and collaterals from portal hypertension may be noted.
A new type of device, the FibroScan (transient elastography), uses elastic waves to determine liver stiffness which theoretically can be converted into a liver score based on the METAVIR scale. The FibroScan produces an ultrasound image of the liver (from 20-80mm) along with a pressure reading (in kPa.) The test is much faster than a biopsy (usually last 2.5-5 minutes) and is completely painless. It shows reasonable corellation with the severity of cirrhosis.[1]
