Optimizing accuracy: a comparative analysis of preoperative liver volumetry in living donor liver transplantation from a surgeon’s perspective – a retrospective cohort study

Accurate prediction of AGW depends on applying optimal correction factors specific to each measurement method. All three methods showed high accuracy with the semi-automated method demonstrating the highest R2 and lowest SE, while the automated method exhibited the lowest error ratio. These findings support the use of cost-effective, software-based volumetry with tailored correction factors to improve donor safety and graft outcomes.
