| description | A system and method for creating magnetic resonance images are provided. The system applies an RF irradiation during a saturation time period at a reference frequency that saturates a range of selected labile spin species of the subject. The system encodes frequency offsets by applying a gradient G1 at least during the saturation time period. The system applies a plurality of slice selection gradients accompanied by a train of RF pulses during a voxel selection time period and a gradient G3 during an acquisition time period. One or more spin/gradient echo signals having information pertaining to at least one of metabolites and metabolite byproducts is acquired to form a CEST medical imaging data set and the CEST medical imaging data set is reconstructed to form a CEST image of the subject including information about the at least one of metabolites and metabolite byproducts within the subject. |
