Keywords: Liver, Liver, Free-breathing MRI, hepatobiliary imaging, 3D cones with golden-angle orderingConventional cartesian T1 weighted 3D spoiled gradient recalled echo imaging with respiratory navigation (3D-SPGR-NAV) can help mitigate motion artifacts in post contrast liver imaging but suffer from respiratory rate dependence. 3D cones trajectories with golden angle ordering (T1g) allow continuous sampling during free-breathing liver imaging. We compared the diagnostic performance of an accelerated T1g (T1gER) versus 3D-SPGR-NAV in liver lesion detection. Two readers reviewed imaging from 35 patients containing 127 hepatic lesions. T1gER was non-inferior to 3D-SPGR-NAV for <5 mm and >=10 mm lesions. 3D-SPGR-NAV was superior for lesions 5-9 mm, possibly due to susceptibility artifact on the T1gER images.
