LB-Conc, EH-Conc, and HW-Conc analyses of iopromide with 3.2 μT saturation power and 6 second saturation time. a) LB-Conc, b) EH-Conc, and c) HW-Conc analyses of CEST at 4.2 ppm estimated kex for the slowly exchanging amide proton. d) LB-Conc, e) EH-Conc, and f) HW-Conc analyses of CEST at 5.6 ppm estimated kex for the rapidly exchanging amide proton. The boundary estimates are shown as gray lines.
