Cardiac Magnetic Resonance Fingerprinting (cMRF) has been recently proposed to reduce scan time by estimating simultaneously T1, T2 and M0 in a single breath-hold acquisition. Additionally, cardiac fat images may carry additional diagnostic information and promising results have been shown for epicardial fat volume quantification, characterisation of cardiac masses and detection of fibro-fatty infiltrations. Here we extend cMRF with a three-point Dixon encoding (Dixon-cMRF) for enhanced myocardium tissue characterisation by providing T1, T2, M0 for both water and fat, from which an additional fat fraction map can be computed. The feasibility of Dixon-cMRF was evaluated in 5 healthy subjects.
