1. A method of providing dynamic magnetic resonance imaging (MRI) of an object in an MRI system, comprising the steps of: a) applying a magnetic resonance excitation from the MRI system to the object; b) reading out magnetic resonance signal encoded in spatial frequency for a plurality of spatial regions with two or three spatial dimensions and a temporal dimension, wherein the read out is pseudo-randomly undersampled in the spatial frequency dimensions and the temporal dimension providing k-space data that is pseudo-randomly undersampled in the spatial frequency dimensions and the temporal dimension; c) using the readout data to create a sequential time series of spatial frequency data sets by generating interpolated data in the spatial frequency dimensions and the temporal dimension; and d) using the sequential time series of spatial frequency data sets to create a temporal series of spatial images.
