Hybrid PET/MR provides a high resolution anatomical and metabolic imaging approach to evaluate human brain tumors. As a novel molecular MRI technique, CEST MRI has been successfully employed in clinical practice. The combination of [18F]-FDG and CEST images will provide further supplementary information on the study of clinic and molecular mechanism for human brain tumors.
