tractography
Pronunciation: track-tog-rah-fee
Computational technique for reconstructing and visualizing white matter fiber pathways from diffusion imaging data.
Full Definition
Tractography is a computational neuroimaging technique that reconstructs three-dimensional representations of white matter fiber pathways using diffusion tensor imaging or diffusion spectrum imaging data. This method enables visualization and quantification of neural connections between brain regions, making it valuable for surgical planning, understanding brain connectivity, and assessing white matter disorders. Tractography algorithms can be deterministic or probabilistic, each with specific advantages and limitations.
