Quantitative T1, T2, T2* and fat fraction (FF) maps are promising imaging biomarkers for the assessment of liver disease. Magnetic Resonance Fingerprinting has been recently proposed for fast T1, T2 and M0 mapping of the liver, however in the presence of high iron or fat concentrations corrections using separately acquired T2* and FF maps are needed. Here we propose a novel approach which enables simultaneous liver T1, T2, T2* and FF maps from a single ~15s breath-hold scan. The proposed approach was evaluated on phantoms, 8 healthy subjects and 2 patients in comparison to conventional mapping techniques.
