CEST acquisition is usually limited to single slice as
different frequency saturations are played out which may
interfere with adjacent slices. On the other hand,
certain applications call for the need of a larger
spatial coverage in slice direction due to the
heterogeneity of the region of interest. An example
could be glioma, which may be associated with edema that
responses differently in APT measurement from the tumor.
In this work, a slice multiplexed CEST acquisition is
proposed, in which two or more slices that experience
the same CEST saturation are simultaneously acquired.
