A method is introduced for combined cardiac CINE and T1, T2, and M0 quantification using MR Fingerprinting throughout the cardiac cycle. Data are acquired continuously using an MRF acquisition and binned by cardiac phase using an external ECG. Undersampled MRF images from all TRs are non-rigidly registered to a consistent cardiac phase before pattern matching in order to generate CINE T1, T2, and M0 maps. CINE-MRF has a breathhold duration (10s) and temporal resolution (25 cardiac phases) similar to conventional CINE scans, while providing both relaxation time measurements and functional information.
