Statistical analysis of the quantitative proton exchange parameters obtained in vitro

Deep MRF-determined glucose-unit concentration in bovine (A) and rabbit (B) liver phantoms were significantly correlated (Pearson’s r > 0.98, p < 0.001) with known concentrations. Similarly, the rNOE proton volume fractions in BSA (C) were significantly correlated (Pearson’s r > 0.99, p < 0.001) with measured concentrations. The deep rNOE-MRF-determined proton exchange rates for all phantoms (right) were successfully decoupled from the concentration dynamics. The black circles represent the mean, and the bars represent the standard deviation.
