Assessment of the hepatic vasculature is critical as part of the pre-liver transplant evaluation. The prevalence of renal insufficiency and concerns regarding gadolinium administration in this cohort has created a need for a non-contrast alternative for vascular assessment. We evaluated the clinical performance of a non-contrast MRA (NCMRA) protocol at 3T in the assessment of the hepatic vasculature in patients with cirrhosis, with contrast-enhanced MRA (CEMRA) as the reference standard. The NCMRA protocol was diagnostic in 94% of subjects, identifying all relevant variant anatomy. Clinically available NCMRA techniques when combined into a comprehensive protocol enable assessment of the hepatic vasculature.
