Claim 0:
1. A magnetic resonance imaging (MRI) system, comprising:
at least one storage device including a set of instructions;
at least one processor in communication with the at least one storage device, wherein when executing the set of instructions, the at least one processor is configured to cause the system to perform operations including:
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.
