Abstract

See full text

A method of providing dynamic magnetic resonance imaging (MRI) of an object in an MRI system is provided. A magnetic resonance excitation from the MRI system is applied to the object. A magnetic resonance signal is read out through k-space for a plurality of 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. The readout data is used to create a sequential series of spatial frequency data sets by generating interpolated data in the spatial frequency dimensions and the temporal dimension. The sequential series of spatial frequency data sets is used to create temporally resolved spatial images.
