Synopsis

This study presents a Pilot Tone (PT) based free-breathing technique for two-dimensional simultaneous quantification of T1, T2, T2*, fat fraction (FF), and water fraction (WF) using quadratic RF phase Magnetic Resonance Fingerprinting (qRF-MRF). We report the quantitative comparison of a cohort of 10 healthy subjects between free-breathing and breath-hold qRF-MRF as well as the comparison to standard clinical protocols. Free-breathing results are comparable to both breath-hold and standard clinical protocols (p > 0.05), indicating the stability and reproducibility of the method.
