The present disclosure related to techniques for implementing Chemical Exchange Saturation Transfer-Magnetic Resonance Imaging (CEST-MRI) sequence generation. The techniques include starting a CEST-MRI scanning process, and generating and transmitting a CEST pre-saturation pulse. When transmission of the CEST pre-saturation pulse has ended, the MRI device generates and transmits a fat-suppression pulse. When transmission of the fat-suppression pulse has ended, the MRI device generates and transmits an excitation pulse. When transmission of the excitation pulse has ended, the MRI device generates and transmits multiple non-slice-selective refocusing square-wave pulses. The present disclosure functions to increase the spatial coverage and MR signal acquisition speed of CEST-MRI imaging.
