T1p relaxation mapping is an intensive technique in terms of acquisition time and specific absorption rate (SAR), making it difficult to acquire in the abdomen. In this study, magnetic resonance fingerprinting (MRF) techniques are applied to simultaneously acquire T1, T2, and T1p relaxation times by adding spin lock pulses before periods of flip angle and TR modulation. MRF and conventional sequences were acquired in phantoms and the abdomen of healthy volunteers. Good agreement was found between the T1, T2, and T1p values from MRF and conventional sequences.
