This study presents a Pilot Tone (PT) based free-breathing technique for two-dimensional simultaneous quantification of T1, T2, T2*, fat fraction (FF), water fraction (WF), and off-resonance. This technique integrates quadratic RF phase-based Magnetic Resonance Fingerprinting (qRF-MRF) and PT navigator to retrospectively provide simultaneous quantification of multiple tissue properties in the abdomen at end-inhalation and end-expiration states.
