Ultrasound (US) still is the first imaging research in the study of patients presenting with chronic liver diseases allowing to assistance physician to know in a fast and effective way the morphologic state of involved organs and also, be Doppler study, to evaluate the features of portal system flow from the quantitative point of view (flow speed) and the qualitative one (flow permeability and direction as well as the presence of collateral circulation vessels). Also allows to assess the structures of the abdominal cavity and to investigate the associated pathologies such as the hepatorenal syndrome. Favoring this technique are the following: its low cost, easy management, reproducibility and lack of interventions with a high sensitivity and specificity level superior to that of other complex techniques of imaging diagnosis by example, the computerized axial tomography (CAT) or the nuclear magnetic resonance (MNR).
