Magnetic resonance fingerprinting (MRF) has shown exceptional promise for simultaneous quantification of T₁ and T₂, based on numerous spiral readouts. We propose an implementation of the MRF paradigm for quantitative imaging using spoiled echo-planar imaging (EPI) with Cartesian readout for simultaneous assessment of T₁ and T₂^* within 10s. Joint T₁ and T₂^* parameter-maps acquired in phantoms with the proposed MRF method are in good agreement with reference measurements and demonstrate high quality in-vivo. This approach offers a rapid supplement to the non-Cartesian MRF portfolio, with potentially increased usability and robustness.
