DTI Analysis: Tensor-based Group Comparison

Objective: To boost statistical sensitivity for group comparisons in comparison to 'traditional' univariate tests.

Example

The figure shows an example of the potential gain in sensitivity using a multivariate tensor test in comparison to the univariate FA test:
