The present invention provides novel methods of accurately and efficiently reconstructing parameter maps in MRI data. In certain embodiments, the methods have reduced data acquisition time or improved spatial resolution when compared to methods standard in the art. In other embodiments, the methods have reduced acquisition and reconstruction time when compared to other acceleration methods in the art in parametric mapping. In other embodiments, the methods are less susceptible to influence of eddy currents when compared to other acceleration methods in the art in parametric mapping.
