Imaging of preoperative liver transplantation in adults: what radiologists should know.

ABSTRACT

Therapeutic strategies for treating patients with liver failure, particularly optimization of liver transplantation, are constantly being refined, with the goal of improving long-term survival with the lowest risk for toxicity in donors and recipients. Optimal planning for liver transplantation requires a multidisciplinary collaboration between the radiologist, hepatologist, clinical oncologist, and transplant surgeon. Radiologists play an essential role in identifying normal and abnormal variant anatomy and other conditions that may be present, a task that is critical for accurate surgical planning. Radiologists also must understand how their findings affect patient preparation. An awareness of the range of indications for liver transplantation, imaging modalities, and current surgical techniques is important to properly evaluate a patient who may undergo liver transplantation. Establishing a pretransplantation definition of the extent of liver disease and thoroughly evaluating the vascular and biliary anatomy are paramount for proper assessment of potential recipients and donors for liver transplantation.
