Relaxation times can be measured efficiently with Magnetic Resonance Fingerprinting (MRF) but further acceleration of MRF is difficult as individual images are already highly undersampled. In this study Hadamard RF-encoding is utilized to acquire four slices simultaneously. It is demonstrated that the proposed method can provide T₁ and T₂ maps for simultaneously acquired slices at 2mm slice thickness.
