The purpose of this investigation was to implement a radial 3D GRE using a golden angle acquisition scheme and KWIC reconstruction for motion-resistant hepatic arterial-phase imaging. These preliminary results show observable suppression of motion artifacts, making this acquisition strategy an effective alternative to cartesian 3D GRE for free-breathing dynamic liver imaging
