We propose a fast one-shot method for obtaining complete Z-spectra for studying MT and CEST phenomena in homogeneous system. The method exploits gradient fields to irradiate a given system and acquire the z-polarization of water protons simultaneously at many frequency offsets. The new method can be useful for fast screening of imaging phantoms and paraCEST contrast agents under different experimental conditions.
