Imaging of the liver can be compromised by motion artifacts which are especially problematic in patients with breathing difficulties. Non-Cartesian k-space sampling trajectories are motion robust and have shown promise in hepatobiliary-phase (HBP) imaging of the liver. Here we demonstrate that free-breathing HBP imaging can be obtained using a 3D cones k-space trajectory with golden angle ordering and extended readout (T1gER). The protocol shows similar performance to a conventional respiratory navigated sequence and can be acquired in less than half the time.
