Fast multi-slice myocardial T1 mapping is of great interest in clinical cardiovascular magnetic resonance (CMR) imaging. This work extends a simultaneous-multi-slice (SMS) model-based reconstruction method for 3-slice myocardial T1 mapping using single-shot Inversion-recovery radial FLASH. Initial results on experimental phantom and one healthy volunteer have demonstrated simultaneous 3-slice myocardial T1 mapping (1.6 x 1.6 x 8 mm3 ) might be feasible within a single inversion recovery of 4 s. More clinical validations of the proposed method will be explored in future studies.
