    Probabilistic tractography is increasingly used to define patient-specific targets for deep brain stimulation (DBS) in various neurological diseases.

  • 2

    The study evaluates errors in the workflow of probabilistic tractography, focusing on the impact of threshold choice, measurement techniques, and normalization.

  • 3

    A cohort of 40 patients who underwent DBS surgery was analyzed to assess the accuracy of electrode positioning relative to specific fiber tracts.

  • 4

    Normalization into a standard space like the Montreal Neurological Institute (MNI) facilitates comparisons across patient cohorts in DBS studies.

  • 5

    The study highlights the need for robust error assessment in tractography workflows to enhance the clinical applicability of DBS targeting.
