High Resolution Tractography Based on Ultra High Field Diffusion MRI


  • Using a combination of reduced field-of-view and partial parallel imaging, called ZOOPPA.
  • Focusing on improving the spatial resolution (down to 0.8 mm isotropic), while keeping acceptable number of directions (60) and signal-to-noise ratio.
  • Reveals fine details of fiber orientation, also in grey matter areas.
  • Tractography of complex crossings within the white matter, and the grey-white-matter interface.
