Diffusion MR & tractography DTI
Diffusion MRI (dMRI) measures the mobility of water molecules in the brain.
Water molecules tend to diffuse along, rather than across, brain white matter fibres.
Consequently, it is possible to map the structure & integrity of major water matter tracts in 3 dimensions, using Diffusion Tensor Imaging (DTI Tractography).
Mapping the structure of white matter tracts, effectively the brain's wiring, in vivo, allows us to understand how different brain regions are connected & how diseases such as stroke, intracranial tumours and schizophrenia affect white matter & cause neurological problems.
The video clip is of a three dimensional rotating colour coded map illustrating the white matter tracts produced from DT-MRI data acquired at the Edinburgh Imaging Facility WGH.
