The free-breathing radial k-space sampling technique is especially useful for patients with limited breath-holding capacity in liver MR imaging, however, its degradation of spatial resolution in the plane compared with the Cartesian sampling is the greatest disadvantage. We assessed the fat-suppressed three-dimensional T1-weighted fast field echo imaging with pseudo-golden-angle radial stack-of-stars sampling technique with gate and track (3D-VANE) compared with the conventional breath-hold Cartesian sampling (BH-eTHRIVE) in hepatobiliary phase imaging. Our results demonstrated that 3D-VANE with thinner effective slice thickness (thin-slice 3D-VANE) achieved comparable interface resolution, less artifact and better image quality compared with BH-eTHRIVE.
