Molecular imaging
Functional molecular imaging such as positron emission tomography (PET) uses various tracers to visualize biological processes such as cell proliferation, membrane biosynthesis, glucose consumption, and uptake of aminoacid analogs 1).
Chemical Exchange Saturation Transfer (CEST) has drawn considerable attention as a novel mechanism of MRI contrast. This method provides more detailed physiological and functional information than conventional MRI and has emerged in the field of molecular imaging 2) 3).
