ECG-triggered cardiac Magnetic Resonance Fingerprinting (cMRF) has been proposed to provide simultaneous myocardial T1 and T2 mapping from a single scan. A “free-running” motion-resolved cardiac MRF (MORE-MRF) approach has been recently introduced to provide T1 and T2 myocardial characterization over the entire cardiac cycle. Here we propose to improve MORE-MRF by exploiting redundancy between the different cardiac phases within a novel motion resolved multi-contrast reconstruction framework. The feasibility of this joint MORE-MRF approach (jMORE-MRF) was evaluated in phantom and healthy subjects and compared against conventional T1 and T2 mapping techniques.
