title: Sonography of Budd-Chiari syndrome.
abstract: OBJECTIVE
  The purpose of this pictorial essay is to review the color Doppler sonographic features of Budd-Chari syndrome.
  
  
  CONCLUSIONS
  Combining color and spectral data, sonography provides hemodynamic and anatomic information about vessel patency and collateral vessel formation. The diagnosis of Budd-Chari syndrome is based on the involvement of hepatic veins although intrahepatic collateral circulation and dilated caudate veins are also important and frequent signs. Half of the patients will develop regenerative nodules that can simulate hepatocellular carcinoma.
