Objectives: To investigate the role of computed tomography (CT) and magnetic resonance imaging (MRI) techniques as non invasive radiological procedures in proper pre-operative assessment of living donor participants in liver transplant procedures. The technological advancement in their techniques are of adding value in minimizing the post operative complication of the donor participants. Methods: Thirty donor candidates were included in the study, submitted to the standardized CT and MRI examinations, and then compared with intra operative results to detect the degree of accuracy and specificity of these non invasive radiological methods and techniques.The detection of pre-operative vascular and biliary anatomical variants are the gold key for prevention of post operative complications.Results: The CT angiographic techniques were the standard technique and their results were of a great sensitivity and specificity reaching almost 100% of the case study population. The CT volumetric technique used were the manual technique and shows results of 90% in comparison to the intra operative volumetric assessment; under-estimating the actual graft liver volume due to technical based and operator based variances. The role of MRI techniques advances is taking the upper hand in hepatic parenchyma assessment and sooner will replace the role of liver biopsy in this field
