CW-XTC MRI depolarization maps using two different saturation pulses with durations of 750 ms (3.1 μT, 13.3°/ms) and 75 ms (31.4 μT, 133°/ms) in the top and bottom rows, respectively. Saturation was applied at five different saturation frequencies: fTP, fRBC, ΔTP, ΔRBC, and CTRL. While the total GP depolarization for on-resonance saturation (fTP, fRBC) is higher for the longer, lower powered saturation pulse, it is lower per unit time. The reverse is true for off-resonance saturation (ΔTP, ΔRBC) due to the lower compartment-selectivity of the higher-powered pulse.
