Overview
CT
Computed tomography is not routinely used in the diagnosis and evaluation of cirrhosis. It is poor at detecting morphologic changes associated with early cirrhosis, but it can accurately demonstrate nodularity and lobar atrophic and hypertrophic changes, as well as ascites and varices in advanced disease.It provides similar information to ultrasonography, but at the expense of radiation and contrast exposure. CT findings may suggest the presence of cirrhosis, but they are not diagnostic. CT portal phase imaging can be used to assess portal vein patency, although flow volume and direction cannot be determined accurately. Computed tomography scan of the abdomen (including the liver, gallbladder, and spleen) can check for tumors and blocked bile ducts and can be used to evaluate liver size and blood flow through the liver.
