Artifacts in dynamic CEST MRI due to motion and field shifts
{Dynamic CEST studies such as dynamic glucose enhanced imaging, have gained a lot of attention recently, as it monitors the uptake and wash-out of glucose shown in tumor models in animals (1,2) and patients with glioblastoma (3,4). The expected CEST effects after injection are rather small in tissue especially at clinical field strengths (1-2 \textpercent). Small movements during the dynamic CEST measurement together with a subtraction-based evaluation can lead to pseudo CEST effects of the same order of magnitude. These artifacts are studied herein.}
