Cardiac Magnetic Resonance Fingerprinting (MRF) has shown promising results for myocardial fibrosis and inflammation characterization. In addition, T1ρ 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 T1ρ 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 T1ρ in a contrast-free single breath-hold MR scan. The proposed approach has been investigated in phantoms and healthy subjects.
