Abstract
Transplantation is considered definitive therapy for acute or chronic irreversible pathologies of the liver, and the increased survival rates are mainly due to improved immunosuppressive therapies and surgical techniques. However, early diagnosis of possible graft dysfunction is crucial to liver graft survival. Diagnostic imaging plays an important role in the evaluation of the liver before and after transplant and in the detection of complications such as vascular and biliary diseases, acute and chronic rejection and neoplastic recurrence. Integrated imaging using color-Doppler, CT, MRI and traditional x-ray reach a high level of sensitivity and specificity in the management of transplanted patients.
