Ultrasound Evaluation of the Portal and Hepatic Veins
WEBApr 15, 2017 · Duplex ultrasound (DUS) evaluation of the hepatic vasculature is best performed using a 2- to 5-MHz curved array transducer in a fasting (8 to 12 hours) patient. Gray-scale imaging of the liver is initially performed and is optimized by using harmonic imaging, spatial compounding, and multiple acoustic windows.

Sonographic Evaluation of the Portal and Hepatic Systems
WEBflow characteristics in the portal and hepatic ves-sels. On occasion, suprahepatic pathologies are reflected in the flow characteristics of the hepatic veins and transmitted to the portal venous system across the hepatic sinusoids. Few definitive duplex findings are pathognomic for portal hyper-tension. Evaluation of the portal venous system is
