Liver transplantation is a successful therapeutic option for patients with chronic liver disease and liver failure in that 1-year survival is greater than 80%. Orthotopic transplantation is usually performed from a cadaveric or living adult donor. The necessary evaluation of recipients and donors prior to transplantation can be successfully performed with computed tomography (CT). CT is useful in determining clinically relevant information for recipients such as size of the caudate lobe, exclusion of advanced hepatocellular carcinoma and other malignancy, patency of the venous system, presence of perihepatic varices, patency of the celiac artery, exclusion of splenic artery aneurysm, and position of iatrogenic venous shunts. CT in living donors may help to determine clinically relevant information about variant hepatic arterial anatomy, source of the artery to segment IV, intraparenchymal anatomy of the hepatic veins and accessory hepatic veins, trifurcation of the portal vein or hepatic duct, liver volume, and fatty change of the parenchyma. Surgical approaches and the imaging findings that influence management are reviewed.
