Real-time US examination: with 3.5 MHz transducer for examination of the liver as regards its size, echotexture, contour hepatic focal lesion, PV, presence or absence of intrahepatic biliary radicle dilatation, porta-hepatis, abdominal lymph nodes and ascites b. Color Doppler US examination of PV: The protocol consisted
