We have investigated the feasibility of concurrent water/fat separation and T1/T2 mapping using spoiled FISP-MR Fingerprinting on a lower-field 0.75T MRI. Water/fat separation is performed in k-space and combined with seven-peak fat-spectrum deblurring and B0-deblurring using multi-frequency interpolation. Matching is performed for water and fat separately and takes B1+ inhomogeneities into account. At 0.75T, T1 was 491ms (liver), 911ms (spleen), 958ms (kidney), 744ms (muscle), and 195ms (fat); and T2 was 77ms (liver), 91ms (spleen), 111ms (kidney), 50ms (muscle), and 105ms (fat).
