diffusion tensor imaging

Abbreviation: DTI
An imaging technique in magnetic resonance imaging to identify the unique directional movement of molecules, esp. water molecules, along muscle and neural tracts. One of its uses is to identify the linkages and structures of white matter tracts in the brain.

Diffusion tensor imaging (DTI)

A refinement of magnetic resonance imaging that allows the doctor to measure the flow of water and track the pathways of white matter in the brain. DTI is able to detect abnormalities in the brain that do not show up on standard MRI scans.
