====== Molecular imaging ======


Functional molecular [[imaging]] such as [[positron emission tomography]] (PET) uses various [[tracer]]s to visualize biological processes such as [[cell proliferation]], membrane biosynthesis, glucose consumption, and uptake of [[aminoacid]] analogs

[[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]]
