Additive value of Non Contrast MRA for evaluation of Mesenteric Arterial Anatomy in Preoperative Planning for Living Donor Liver Transplants.

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.
