The major challenges for 3D whole-heart MRI are long acquisition times and respiratory motion. Here a fast and highly efficient 3D whole-heart acquisition scheme is presented. It combines the ideas of Radial Phase Encoding(RPE) allowing for high acceleration factors and Phase Ordering with Automatic Window Selection(PAWS) yielding high navigator efficiency. A new phase encoding scheme is proposed to ensure a short scan time for isotropic high resolution images.
