LB-Conc, EH-Conc, and HW-Conc analyses of simulated CEST MRI results generated with a 3.5 μT saturation power, 10 second saturation time, 1200 Hz chemical exchange rate, and 10 second T1w relaxation time. A representative a) LB-Conc, b) EH-Conc, and c) HW-Conc fitting of simulated CEST results were used to estimate kex. d) LB-Conc, e) EH-Conc, and f) HW-Conc accurately estimated slow kex, but failed to accurately estimate fast kex. The T1w relaxation time did not affect the accuracies of these estimates.
