Computed tomography in the evaluation of cirrhosis and portal hypertension

Patients with cirrhosis present a continuing diagnostic and therapeutic challenge. The status of their disease frequently changes, necessitating intensive serial evaluation. CT is an invaluable tool in the management of these patients because it can noninvasively provide vital information concerning liver size, contour, and occasionally hepatic parenchyma. More importantly, CT can demonstrate superficial and deep varices, assess the patency of the extrahepatic portal system, and detect other complications including ascites, hepatic steatosis, hemochromatosis, and hepatocellular carcinoma.
