Abstract

The role of imaging in patients with cirrhosis is to characterize the morphologic manifestations of the disease, evaluate the hepatic and extrahepatic vasculature, assess the effects of portal hypertension, and detect and characterize hepatic tumors, especially differentiating hepatocellular caricnoma (HCC) from other tumors. CT plays a major role in the imaging of the liver. The recent development of multidetector row CT (MDCT) technology has helped CT to continue to excel in its currently established indications such as detection and characterization of hepatic lesions. HCC is the fifth most common tumor in the world and the incidence is expected to increase in the future due to hepatitis viral infections and increasing cirrhosis incidence. Approximately 90% of patients with HCC have cirrhosis. The imaging criteria of HCC are usually based on the vascular findings of HCC (e.g. arterial enhancement followed by washout in the portovenous and equilibrium phase). To understand the hemodynamics of HCC is important for the precise imaging diagnosis and treatment since there is a good correlation between their hemodynamics and pathophysiology. In this chapter, the most important and prevalent findings of HCC which can be evaluated by CT scans, and current diagnostic criteria were discussed. In addition, the imaging features of atypical HCC as well as frequent HCC mimickers in cirrhotic liver were also discussed.
