a) T1, T2, and proton density maps generated with MRF-QUEST in a phantom containing vials with materials of different relaxation times. The correlations of b) T1 values and c) T2 values from MRF-QUEST to the spin echo methods. The efficiencies of MRF-QUEST at different d) T1 and e) T2 values are compared to the results generated from FISP-based MRF method.
