Tractography
Pronunciation: /trak-TOG-ra-fee/
Imaging technique that reconstructs white matter fiber pathways in the brain using diffusion tensor imaging data.
Full Definition
Tractography is an advanced neuroimaging technique that uses diffusion tensor imaging data to create three-dimensional reconstructions of white matter fiber tracts in the brain. In neuro-oncology, tractography is invaluable for pre-surgical planning as it visualizes major white matter pathways that may be at risk during tumor resection. The technique helps surgeons plan approaches that minimize damage to critical connections between brain regions, potentially preserving neurological function while achieving maximal tumor removal.
