We investigate the use of a novel reduced FOV CEST
method that allows us to zoom in the prostate region
that helps delineating the tumor region from the benign
region and improves accuracy in grading using CEST. The
use of reduced FOV CEST in prostate was validated by
comparing the APT map and MTRasym to those obtained
using normal CEST, highly consistent results were
obtained despite its lower intrinsic SNR. Reduced FOV
CEST has the advantage of revealing the heterogeneity of
the prostate, which may be difficult due to the
constrained portion of the prostate region in normal FOV
image.
