• Non-contrast-enhanced magnetic resonance angiography
• Inflow inversion recovery (IFIR)
• Balance steady state free precession (bSSFP)
• Contrast-enhanced magnetic resonance angiography
• Liver donors
• Liver transplant

The purpose of this study is to compare diagnostic quality, inter-observer variability and agreement of non contrast enhanced MRA (NC-MRA) with contrast-enhanced MRA (CE-MRA) in the evaluation of hepatic arterial anatomy. 20 potential liver donors were included in this retrospective study. NC-MRA, CE-MRA and combined data sets were randomized and reviewed by two readers. Reference standard was consensus by two senior radiologists using all data including CTA. There was no difference in IQ or diagnostic confidence between NC-MRA, CE-MRA or combined data for either reader but the arterial origin of segment IV was successfully identified on NC-MRA when CE-MRA was suboptimal.
