Claim 1:
2. A magnetic resonance imaging (MRI) method implemented on a computing device having at least one processor and at least one storage device, comprising:
obtaining a plurality of signals relating to a region of interest (ROI) of an object acquired by applying to the object a plurality of chemical exchange and saturation transfer (CEST) preparations with a plurality of offset frequencies, the plurality of signals relating to the ROI being acquired based on a multitasking technique;
generating an image of the ROI based on the plurality of signals; and
sending the image to a terminal for display, wherein
the plurality of CEST preparations are configured to excite proton exchange of a substance in the ROI;
the plurality of CEST preparations are divided into one or more groups, each of the one or more groups comprising multiple CEST preparations with a same offset frequency among the plurality of offset frequencies; and
after a last CEST preparation in each of the one or more groups is applied to the object, the substance reaches a saturation degree that exceeds a saturation threshold.
