Cardiac MR Multitasking has been shown to acquire simultaneous T1 and T2 maps without ECG or breath-holds. Simultaneous multi-slice (SMS) acquisition has the potential to increase the clinical value of CMR by decreasing the exam time. In this work, we developed an SMS, non-ECG and free-breathing MR Multitasking technique and demonstrated that it had consistent T1, T2 measurements when compared with the overall-slower series of reference protocols (MOLLI, T2-prep FLASH).
