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
