Overview
Ultrasound
Ultrasound is routinely used in the evaluation of cirrhosis, where it may show a small and nodular liver in advanced cirrhosis along with increased echogenicity with irregular appearing areas. Ultrasound may also screen for hepatocellular carcinoma, portal hypertension and Budd-Chiari syndrome (by assessing flow in the hepatic vein).
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]
Other tests performed in particular circumstances include abdominal CT and liver/bile duct MRI (MRCP).
