Objective To explore the value of ultrasound score for staging liver fibrosis in minipigs.Methods Twelve minipigs of liver fibrosis were induced by 40％ carbon tetrachloride (CC14) dissolved in fat emulsion by intraperiton-eal injection (0.25 mL/kg body weight for 16 weeks) and feeding (0.75 ml/kg body weight for subsequent 5 weeks because of the chemical adhesions resulting from the injection) until the stage of liver cirrhosis on the 21st week.In addition, a 5 ％ alcohol-water mixture was used as the sole drinking water.On the O, 5th,9th, 16th and 21st weekend after the beginning of the modeling , hepatic parenchymal echo, gallbladder wall and intrahepatic vessels were observed by low-frequency ultrasound, liver capsule and edge were viewed by highfrequency ultrasound.
