Tractography can be sensitive to a number of parameters.
However, there are few methods for quantifying such
sensitivity. We demonstrate a means for quantitative
comparison of pathways by comparison with an ensemble of
tracks. We apply the method to compare the results of
two probabilistic tractography methods: a
computationally intensive Monte Carlo (MC) approach and
fast partial differential equations (PDE) that is
designed to rapidly replicate the results of the MC
approach.
