Indications
identifies
- liver size, hepatomegaly
- diffuse parenchymal changes (increased echogenicity, NOT specific for fatty liver)
- focal liver masses
- gallstones
- gallbladder thickening
- biliary tract dilation
- hepatic vein obstruction or portal vein obstruction
- presence of collateral vasculature suggestive of portal hypertension with doppler
- splenomegaly
- presence of ascites
Real time imaging:
- biopsy of focal hepatic lesions
- aspiration of small amounts of ascites
- high mean flow velocity through hepatic artery predicts poor response to beta-blocker therapy[2]
Procedure
- contrast-enhanced ultrasound with sulfur hexafluoride microbubbles (SonoVue) recommended for evalution of uncharacterized liver lesions [NICE]
