What is Tractography?

What is Tractography?

Tractography is a 3D modelling technique that uses data from diffusion MRI to visually represent nerve tracts.

It's used in neuroscience to identify white matter pathways in the living human brain.

These pathways are essential for understanding how the brain functions in both normal and diseased states.

Tractography uses special techniques of magnetic resonance imaging (MRI) and computer-based diffusion MRI.

It measures the rate of water diffusion between cells to create a map of the body's internal structures. The results are presented in two- and three-dimensional images called tractograms.

Tractography has some limitations also described in this E-Booklet

Thus, it is strived in this Booklet to precisely describe the followings:

How tractography works.
The challenges of crossing fibres.
Constrained Spherical Deconvolution (CSD) for whole brain cortical tractography.
The importance of CSD for generating accurate tractography, along with relevant IMAGES for better understanding this current neuroimaging toolset.
