The CEST-FISP MRI pulse sequence with respiration gating.26 The respiration gating was adjusted to allow the start of acquisition in a 200 ms window (thick black line) that started 300 ms after inhalation. The series of saturation pulses typically ended within a respiration gating window, and the FISP acquisition was immediately started. Due to variable breathing rate, additional 600 ms saturation pulses was added to the saturation period until the total saturation period ended within a respiration gating window.
