AB  - Radiofrequency (RF) heating of tissue during magnetic resonance imaging (MRI) is 
      a known safety risk in the presence of active implantable medical devices 
      (AIMDs). As a result, access to MRI is limited for patients with these implants 
      including those with deep brain stimulation (DBS) systems. Numerous factors 
      contribute to excessive RF tissue heating at the DBS lead-tip, most notable being 
      the trajectory of the lead. Phantom studies have demonstrated that looping the 
      extracranial portion of the DBS lead at the surgical burr hole reduces the 
      heating at the lead-tip; however, clinical implementation of this technique is 
      challenging due to surgical constraints. As such, the intended looped trajectory 
      is usually different from what is implanted in patients. To date, no data is 
      available to quantify the extent by which surgical trajectory modification 
      reduces RF heating of DBS leads compared to the typical surgical approach. In 
      this work, we measured RF heating of a commercial DBS system during 3 T MRI, 
      where the trajectory of the lead and extension cable mimicked lead trajectories 
      constructed from postoperative CT images of 13 patients undergoing modified DBS 
      surgery and 2 patients with unmodified trajectories. Two manually created 
      trajectories mimicking typical heating cases seen in the literature were also 
      evaluated. We found that modified lead trajectories reduced the average heating 
      by 3-folds compared to unmodified lead trajectories.Clinical Relevance- This 
      study evaluates the performance of a surgical modification in the routing of DBS 
      leads in reducing RF-induced heating during MRI at 3 T.
