Detection and characterisation of focal liver lesions using contrast-enhanced ultrasonography
Detection and characterisation of focal liver lesions using contrast-enhanced ultrasonography

Introduction
The liver is a unique organ in that it has a dual blood supply.About one-third of the total blood supply in healthy liver comes from the hepatic artery while the remainder comes from the portal vein.Malignant tumours, however, are preferentially supplied by the hepatic artery. In cirrhotic liver, the portal venous supply is markedly reduced, and blood flow from the hepatic artery increases in compensation. These differences in hepatic haemodynamics provide both opportunities and – in the case of cirrhotic liver – challenges for the differential diagnosis of focal liver lesions using contrast-enhanced ultrasonography(US).
