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.
