Bootstrap Analysis of DT-MRI Tractography Techniques: Streamlines and Tensorlines

Introduction Diffusion tensor MRI has been used to reconstruct white matter connections in the human brain [1,2]. The common approach in tracking the white matter fibers trajectories through the brain has been the use of the tensor major eigenvector in order to assess the propagation direction. As an alternative approach, tensorlines [3,4] was developed using the entire tensor, D, by defining a deflected vector:
