CEST imaging generally requires long scanning time which
significantly hampers clinical translation. In this
work, we introduce an accelerated CEST imaging using a
compressed sensing image reconstruction of radial
acquisition trajectory with a golden-angle ordering
scheme combined with parallel imaging technique. We
tested this method in a creatine phantom and
in
vivo
muscle
before and after exercise. This work provides a
proof-of-concept of new method for future clinical
application.
