In this project, we proposed a fast 3D CEST MRI technique called GraspCEST, which is based on the combination of CEST-prepared stack-of-stars golden-angle radial sequence and multicoil compressed sensing reconstruction. Using this technique, we were able to perform lipid suppressed, free-breathing 3D CEST imaging of the liver. We have demonstrated that it is possible to accelerate imaging speed and achieve full Z-spectra acquisition of the liver within 5 min. The GraspCEST technique can be a useful tool in studying glycoNOE in the liver.
