Scalars

Diffusion Scalars

Preprocessing of diffusion sequences and extraction of whole brain scalars (using dtifit), including: 

  • Fractional anisotropy, mean diffusivity, axial diffusivity, and radial diffusivity
  • Image cleaning using FSL's top-up and eddy

Kurtosis Scalars

Preprocessing of multi-shell diffusion sequences (often called diffusion kurtosis) and extraction of whole brain scalars (using dtifit), including:

  • Fractional anisotropy, mean diffusivity, axial diffusivity, and radial diffusivity
  • Image cleaning using FSL's topup and eddy
