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.
