We apply a 3D continuous golden-angle radial sparse parallel (GRASP) sequence to gadoxetic acid-enhanced imaging of the liver at 3 T. Arterial phase imaging may need high spatial and temporal resolution as well as correct timing of capturing arterial enhancement to obtain hemodynamic information of the tumor. Continuous golden-angle radial sampling provides a flexible retrospective selection of temporal window. We develop a technique that identifies the arterial peak from high temporal resolution data and reconstructs arterial phases with different temporal windows. The characteristics of hepatic arterial images after retrospective temporal resolution selection are demonstrated.
