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.
