The inhomogeneity of the main magnetic field (B0) often results in degraded quality of CEST images. Currently, various B0 mapping methods have been used to correct the B0 inhomogeneity of CEST images. Motion inevitably happens between B0 mapping and CEST scans, which, however, is usually ignored in the current CEST processing pipeline. Here, we show that the inclusion of B0 mapping images into the motion correction process improved the quality of the CEST maps, and statistically significantly improved the uniformity indices. Thus, we suggest adding the motion correction of B0 mapping data step into the standard CEST processing pipeline.
