Zusammenfassung
MRI of hyperpolarized C is a molecular imaging technique with enormous clinical potential, yielding a tremendous increase in signal. The non-renewable nature of hyperpolarization however, makes the imaging and data interpretation process highly sensitive to accurate knowledge about excitation flip angles (FA). Thus, estimation of B1 and its distribution for the specific C coil used is required to optimally calibrate the measurements. Several approaches to calibrate B1 have been proposed. As an interesting alternative, B1+ mapping with magnetic resonance fingerprinting (MRF) has been shown to be highly precise, especially at low FA, and has the potential to estimate additional parameters like T1 time, T2 time and metabolic conversion rate. The purpose of this study was to demonstrate the proof-of-concept of an MRF-based B1+ estimation for C experiments.
