Previous studies showed that the postoperative effectiveness of DBS contacts depends on the distance to the dentatorubrothalamic tract (DRTT). Here, we investigated whether the most effective DBS contact could be determined from calculating stimulation overlap with the individual DRTT. Seven ET patients with bilateral thalamic deep brain stimulation were included retrospectively. Tremor control was assessed for each contact during test stimulation with 2mA. Individual DRTTs were identified from diffusion tensor imaging and contacts were ranked by their stimulation overlap with the respective DRTT in relation to their clinical effectiveness. A linear mixed-effects model was calculated to determine the influence of the DRTT overlap on tremor control. In all investigated DBS leads, the contact with the best clinical effect was the contact with the highest or second-highest DRTT overlap. At the group level, the DRTT-overlap explained 26.7% of the variance in the clinical outcomes (p &lt; 0.001). Our data suggest that the overlap with the DRTT based on individual tractography may serve as a marker to determine the most effective DBS contact in ET patients and reduce burdensome clinical testing in the future.<\/jats:p>","DOI":"10.3390\/brainsci10121015","type":"journal-article","created":{"date-parts":[[2020,12,20]],"date-time":"2020-12-20T22:33:53Z","timestamp":1608503633000},"page":"1015","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Selecting the Most Effective DBS Contact in Essential Tremor Patients Based on Individual Tractography"],"prefix":"10.3390","volume":"10","author":[{"given":"Jan","family":"Petry-Schmelzer","sequence":"first","affiliation":[{"name":"Department of Neurology, Faculty of Medicine and University Hospital Cologne, University of Cologne, 50923 K\u00f6ln, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7023-146X","authenticated-orcid":false,"given":"Till","family":"Dembek","sequence":"additional","affiliation":[{"name":"Department of Neurology, Faculty of Medicine and University Hospital Cologne, University of Cologne, 50923 K\u00f6ln, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julia","family":"Steffen","sequence":"additional","affiliation":[{"name":"Department of Neurology, Faculty of Medicine and University Hospital Cologne, University of Cologne, 50923 K\u00f6ln, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hannah","family":"Jergas","sequence":"additional","affiliation":[{"name":"Department of Neurology, Faculty of Medicine and University Hospital Cologne, University of Cologne, 50923 K\u00f6ln, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8849-4233","authenticated-orcid":false,"given":"Haidar","family":"Dafsari","sequence":"additional","affiliation":[{"name":"Department of Neurology, Faculty of Medicine and University Hospital Cologne, University of Cologne, 50923 K\u00f6ln, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gereon","family":"Fink","sequence":"additional","affiliation":[{"name":"Department of Neurology, Faculty of Medicine and University Hospital Cologne, University of Cologne, 50923 K\u00f6ln, Germany"},{"name":"Cognitive Neuroscience, Institute of Neuroscience and Medicine (INM-3), Research Center J\u00fclich, 52428 J\u00fclich, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Veerle","family":"Visser-Vandewalle","sequence":"additional","affiliation":[{"name":"Department of Stereotactic and Functional Neurosurgery, Institute of Medicine and University Hospital Cologne, University of Cologne, 50923 K\u00f6ln, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Barbe","sequence":"additional","affiliation":[{"name":"Department of Neurology, Faculty of Medicine and University Hospital Cologne, University of Cologne, 50923 K\u00f6ln, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,12,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"461","DOI":"10.1056\/NEJM200002173420703","article-title":"A Comparison of Continuous Thalamic Stimulation and Thalamotomy for Suppression of Severe Tremor","volume":"342","author":"Schuurman","year":"2000","journal-title":"N.
