DTI
Pronunciation: DEE-tee-EYE
Also written as: DTI — Diffusion Tensor Imaging
Diffusion tensor imaging, an advanced MRI technique that maps white matter fiber tracts in the brain.
Full Definition
Diffusion tensor imaging (DTI) is a specialized magnetic resonance imaging technique that measures the diffusion of water molecules along white matter fiber tracts in the brain. This imaging method provides detailed information about the microstructural integrity of white matter pathways, allowing clinicians and researchers to visualize neural connections and detect subtle changes in brain structure. DTI is particularly valuable in diagnosing conditions affecting white matter, tracking disease progression, surgical planning for brain tumors, and research into neurological and psychiatric disorders. The technique generates metrics such as fractional anisotropy and mean diffusivity to quantify tissue properties.
Usage
Usage note: Always spell out on first use in patient-facing documents.
