Magnetization transfer (MT) techniques provide tissue contrast which depends mainly on the concentration of macromolecules. The magnetization transfer phenomenon is determined by the restricted macromolecular protons and is quantified by the magnetization transfer ratio (MTR). Since many macromolecular structures are implicated in the secretory activity of the pituitary gland …
