This study was performed to assess the additive value of non-contrast enhanced MRA (NC-MRA) using a respiratory gated 3D SSFP based sequence for evaluation of liver arterial anatomy in patients under going contrast enhanced MRA (Gd-MRA) for preoperative planning for potential liver donation. Liver donor arterial anatomy evaluation is not significantly improved by the addition of NC-MRA but can be useful when GD-MRA is suboptimal and further improvements in sequence design would be helpful to limit contrast exposure in this population and increase efficiency of patient throughput.
