A significant limitation of deterministic tractography methods is the lack of information they provide regarding the error in the tracking procedure in any given experiment. Without this knowledge it is not possible to know how much confidence we should have in the observed results. Probabilistic tractography methods attempt to overcome this limitation by explicit characterization of the confidence with which connections may be established through the diffusion MRI data set. This chapter describes the range of probabilistic tractography techniques, their dependencies on source data and models of fiber orientation and some of their outstanding limitations.
