Abstract EN
Diffusion tensor imaging (DTI) is considered to be a promising tool for revealing the anatomical basis of functional networks.
In this study, we investigate the potential of DTI to provide the anatomical basis of paths that are used in studies of effective connectivity, using structural equation modeling.
We have taken regions of interest from eight previously published studies, and examined the connectivity as defined by DTI-based fiber tractography between these regions.
The resulting fiber tracts were then compared with the paths proposed in the original studies.
For a substantial number of connections, we found fiber tracts that corresponded to the proposed paths.
More importantly, we have also identified a number of cases in which tractography suggested direct connections which were not included in the original analyses.
We therefore conclude that DTI-based fiber tractography can be a valuable tool to study the anatomical basis of functional networks.
