Both high temporal and high spatial resolutions of DCE-MRI are required for screening patients with high risk of the breast cancer using pharmacokinetic model analyses. The objective of our study was to investigate the feasibility of using a novel image reconstruction method that combines compressed sensing and parallel imaging for radial trajectories (k-t RASPS) for DCE-MRI study of the breast cancer. Unilateral breast MRI was performed with six patients using golden-angle radial VIBE pulse sequence. Our results demonstrate that high temporal resolutions images (up to 1.2 s/frame) can be reconstructed without noticeable temporal blurring.
