Diffusion Tensor Imaging

Diffusion tensor imaging (DTI) is a magnetic resonance imaging (MRI) technique used to provide information about the structural connections among brain regions, in particular the brain’s white matter, which contains the fibers that connect nerve cells.

DTI uses specific radio frequency and magnetic field-gradient pulses to track the movement of water molecules in the brain. In most brain tissue, water molecules diffuse along the length of axons, components of nerve cells that conduct impulses away from cell bodies. Axons are coated with myelin, a soft white material of lipid and protein that holds in water molecules.  Researchers can create pictures of these axons by analyzing the direction of water diffusion.
