Abstract
Liver transplantation is the accepted treatment for patients with irreversible hepatocellular failure and in selected patients with hepatocellular carcinoma. Survival rate has continued to improve as a result of careful patient selection, as well as improvements in graft preservation, surgical techniques and immunosuppression. Radiology is an essential part of a successful transplant programme; assessment of the transplant candidate, recognition of post-transplant complications, interventional treatment and follow-up of transplant recipients require accurate diagnostic imaging and interventional radiological input.
