Magnetization transfer (MT), as commonly used in biomedical MRI, refers to the transfer of longitudinal magnetization from the hydrogen nuclei of water that have restricted motion to the hydrogen nuclei of water that moves with many degrees of freedom. The water with restricted motion is generally conceived as being bound to macromolecules,such as proteins and lipids through a series of hydrogen bonds. The free water pool is the bulk water of the cytosol. In this context, the hydrogen nuclei are typically referred to simply as protons.
