Data quality, NAMIC DTI pipeline

  • Issues?

ROI definitions and impact on different methods

  • Force all methods to use the same ROIs?

- For streamline methods larger ROIs than the tract itself good

Methods:

  • Streamline Slicer2 (Sonia)
  • Streamline Fiberviewer (Casey)
  • Stochastic Slicer3 (Tri)
  • Shortest path, volumetric (John)
  • Shortest path, volumetri (Tom)

Review and define metrics to compare results, which methods to compare?

Current metrics: tensor invariants (FA, trace, mode, norm), volume, length.

  • 12 different tracts
  • Tracts voxelized -> volumetric result from tracts
  • Missing parts of a tract, how should be penalized?
  • Statistics along the tracts, should we sum along the tract to get one measure?
  • Distributions across the tract
  • Atlas (Casey)
