Elastography is one of these, which allows evaluation of hepatic fibrosis by measurement of hepatic stiffness. Thus, recently, new diagnostic tools have been introduced to evaluate the mounting fibrotic damages in the liver. However, before this process becomes irreversible, there are several degrees of injuries that progressively accumulate.
The final step of hepatic changes in cirrhosis is diffused fibrosis. Ībdominal US in advanced cirrhotic condition shows hepatic changes do to regeneration process and fibrosis ( a, b), with also ascites, that is identified as anechoic fluid around the perihepatic space (star) When necessary, basic B-mode study should be completed by colour-Doppler technique. A complete US study of the liver requires systematic study through longitudinal, axial and oblique scans it also includes the evaluation of intrahepatic vascular structures (intrahepatic and portal veins) and the study of the gallbladder. Segment I is an autonomously vascularised lobe situated behind the venous ligament. The right portal vein separates anterior and posterior segments of the right lobe, the left portal branch, instead, identifies Segment II and Segment III on the left hepatic lobe. 1), so that each one has its own vascular peduncle. According to Couinaud Codification, each lobe is composed of many segments on the basis of portal and venous branches (Fig. Liver is located in the right upper quadrant of the abdomen and is divided into a right lobe on the right-hand side of the falciform ligament and a left lobe on the opposite side, while the quadrate and the caudate lobes are near to the hilum.
