Core Tip

Core Tip: Liver transplantation (LT) is the golden standard in the treatment of end stage liver disease. The main limiting factor in the application of LT is graft shortage and over the years, many strategies have been developed in order to increase graft availability, such as living donor liver transplantation and split liver transplantation. In these strategies, liver volume assessment is of paramount importance in the success of LT. In this preliminary proof-of-concept study, we evaluated the use of light detection and ranging (LIDAR) technology for ex vivo measurement of hepatic grafts. Preliminary data indicate that LIDAR scanning of liver grafts is a safe, cost-effective, and feasible method of ex vivo determination of whole liver volume and mass.
