Clinical myocardial T1 mapping protocols typically acquire three 2D slices, each obtained in a separate breath-hold; this is only feasible in patients able to do sequential breath-holds. We propose SMS-ProMyoT1 which integrates simultaneous multi-slice (SMS) with open-source ProMyoT1, previously implemented with Pulseq, to obtain all slices in a fast single shot. SMS-ProMyoT1 differs from previous implementations by combining blip-bSSFP with VERSE-multiband for RF modulation, and auto-calibrated blip patterns for a fast self-contained sequence. The method was successfully applied both in a reference phantom and in-vivo.
