Reduced FOV chemical exchange transfer saturation

CEST acquisition usually consists a series of frequency saturation, which constraint the acquisitions to be single shot for achieving feasible scan time. Hence the resulting images are associated with limited resolution as well as image distortions. However the region of interest (ROI) of CEST study is often spatially limited and known at prescription. In this study, a reduced FOV excitation method is used to exploit this knowledge, and its benefits are demonstrated in a prostate CEST acquisition.
