Extracting brain connectivity from diffusion MRI

A short introduction of diffusion magnetic resonance imaging (dMRI) tractography methods will be given. dMRI is an MRI modality that has been popular for the last five years and is greatly used for imaging the white matter in the brain. It is one of the first methods that was able to visualize and quantify the organization of white matter in the human brain. The diffusion tensor MRI (DT-MRI) is an MRI modality that is used for relating the image intensities to the relative mobility of endogenous tissue water molecules. Other methods that were discussed were the PDD method and the stochastic method.
