Cardiac Magnetic Resonance Fingerprinting (MRF) has shown promising results for myocardial fibrosis and inflammation characterization. In addition, T mapping has shown promising results for detection of focal and diffuse myocardial fibrosis without the need of exogenous contrast agents. However, multiparametric T1, T2 and T mapping requires sequential acquisitions under several breath-holds, that can lead to non-registered maps and bias due to inter-parameter dependencies. In this work we propose a cardiac MRF acquisition scheme for simultaneous quantification of myocardial T1, T2 and T in a contrast-free single breath-hold MR scan. The proposed approach has been investigated in phantoms and healthy subjects.
