Magnetization Transfer

Magnetization transfer (MT) is an MRI technique that detects interactions between free water molecules and bound molecules within tissues. When a special radiofrequency pulse is applied, it selectively affects the bound molecules, which then transfer their magnetization to the free water molecules. This transfer alters the MRI signal, providing information about tissue composition and structure. MT helps distinguish different tissue types, identify abnormalities, and improve imaging contrast—especially useful for analyzing brains, muscles, and other complex tissues, aiding in diagnosis and research without invasive procedures.
