  CEST suffers from two main problems long acquisitin times or restricted
coverage as well as incoherent protocol settings. In this paper we give
suggestions on how to optimise your protocol settings fro CEST and present one
setting for APT CEST. To increase the coverage while keeping the acquisition
time constant we suggest using a spatial temporal Compressed Sensing approach.
Finally, 1.8mm isotropic whole brain APT CEST maps can be acquired in a little
bit less than 2min with a fully integrated online reconstruction. This will
pave the way to an even further clinical use of CEST.
