Abstract
Preoperative evaluation of donors for living-donor liver transplantation aims to select a suitable donor with optimal graft quality and to ensure donor safety. There are minor variations in the donor selection process among different centers, but the safety of the donor remains central to the entire process. The potential donors are evaluated in a stepwise manner including medical, physical, laboratory, psychosocial, and imaging assessment to disqualify unsuitable donors as early as possible in the evaluation process. The main goal of the imaging study is to provide an accurate picture of liver vascular anatomy and liver volume measurement for surgical guidance or for exclusion of unsuitable donors. All imaging studies can now be obtained using noninvasive modalities, thereby decreasing the risk associated with the donor evaluation process. This article describes the donor selection practice in our center including the details of the imaging evaluation.
