2D Cardiac Magnetic Resonance Fingerprinting (cMRF) has been previously proposed to provide co-registered T1/T2 maps from a single breath-hold scan. Gradient Spoiled gradient echo (GRE) readout is conventionally employed for 2D cMRF. RF-spoiled readouts (FLASH) have reduced signal-to-noise ratio but are less sensitive to field inhomogeneities that may bias the parametric maps (if not encoded in the MRF sequence). Here we compare the performance of FLASH and GRE readouts for simultaneous T1/T2 mapping in 2D cMRF. Phantom and in-vivo results showed that both sequences produce comparable maps and reproducible values, however GRE-cMRF presented larger underestimations for T1 and T2.
