Snapshot whole brain CEST MRI at 3T with 3D-EPI

{CEST MRI provides metabolite-based contrasts but often suffers from poor volume coverage or spatial resolution. We optimized and included a snapshot 3D-EPI readout and propose a suitable post-processing pipeline to generate CEST contrast in the whole brain at clinical B0\textequals3T. It is shown that CEST MRI with 1.8mm isotropic nominal resolution at a field of view of 256x224x156mm\mbox{$^3$} is feasible within 4.3s per presaturation frequency offset. The approach is adaptable for any presaturation scheme. Exemplarily low power saturation was performed and fitted Lorentzian amplitudes gave a coefficient of variation \textless8.5\textpercent across three healthy subjects.}
