Pulse sequence diagram of standard (left) and wideband (right) saturation RF pulse modules. The pulse duration of standard and wideband modules was 11 and 18 ms, respectively. Note, 500 Hz corresponds to the transmit RF field (when normalized by the gyromagnetic ratio of water) needed to achieve 90° rotation by a rectangular RF pulse with 0.5 ms pulse duration. An identical gradient cycling scheme was used by the two saturation pulse modules.
