The purpose of this study was to evaluate the clinical feasibility of time-resolved three-dimensional contrast-enhanced dynamic MR imaging of the whole liver with parallel imaging technique during a single breath-hold, and to assess the utility of continuous imaging from early-arterial through late-arterial phase for evaluating hypervascular HCCs. The study included 82 patients with 51 HCCs. This technique allows the capture of the distinct arterial and portal phases, obviating the use of timing bolus or contrast detection methods, and has a potential to evaluate transitional hemodynamics of hypervascular HCCs during the early-arterial through early-portal phase due to excellent temporal resolution.
