Like other magnetic resonance (MR) techniques before it, magnetic resonance fingerprinting (MRF) was developed and applied in the traditional context of a precisely calibrated and uniform radiofrequency excitation field. Plug & Play Parallel Transmission (PnP-PTX), on the other hand, was designed to liberate MRF from these constraints. We evaluate the impact of excitation field non-uniformities on abdominal MRF experiments at different field strengths, and show that PnP-PTX has the potential to alleviate these challenges, and thereby opens opens up a new route towards robust, quantitative, whole-body MRI for ultra-high-field systems.
