A time-resolved hybrid radial/Cartesian acqusition, PR-TRICKS, is combined with a newly developed method, HighlY constrained back PRojection (HYPR) reconstruction, provides artifact-free images with overall Nyquist undersampling factors of 200 or more. This greatly improves both the temporal and spatial resolution.
