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.
