Chronic renal insufficiency commonly accompanies end-stage liver disease affecting 18-39% of patients. Renal insufficiency adversely impacts the pre-transplant liver vascular assessment, which is necessary to determine suitability for liver transplantation. A comprehensive non-contrast enhanced MRA protocol using a combination of different techniques enables complete assessment of the liver vasculature in the majority of patients. Our study evaluates the performance of a non-contrast MRA protocol for the pre-liver transplant vascular evaluation, using contrast-enhanced MRA as the standard of reference.
