“…After that the distances of the target from the midcommissural point in all 3 planes were measured. Using these measurements the target point was marked on the CT image (and left on the screen for postimplantation verification), and stereotactic coordinates for this point were measured using a technique previously described [19] . In the case of the STN, which was clearly visible on the MR images, the dorsal-lateral part of the nucleus was chosen as the target.…”

Background: In order to view the position of the deep brain stimulator (DBS) lead in relation to the stereotactic target on 3-tesla magnetic resonance (3T-MR) images prior to the conclusion of the procedure, intraoperative postimplantation computed tomography (CT) images were fused with preoperative 3T-MR images. The method to do this is described and discussed in this paper. Methods: Over the last year, this method was used for 8 procedures: 6 for subthalamic nucleus and 2 for ventral-intermediate nucleus of the thalamus. The procedures were done on the CT table in a stereotactic frame. CT and MR images plus coordinates from the Schaltenbrand atlas were used to plan the target. After the lead had been placed at the target, intraoperative CT images were obtained and fused with preoperative 3T-MR images prior to the conclusion of the procedure. If error was detected in the lead position, it was corrected. Results: Errors in the x-coordinate were detected in 2 patients. These errors were corrected prior to the conclusion of the procedures. Conclusion: This is a simple method to intraoperatively visualize DBS lead position on high-quality 3T-MR images. It gives the surgeon the capability to detect errors and correct them prior to the conclusion of the procedure.

“…In this case, the middle of the foramen was targeted. The coordinates were measured directly on the CT image and then adjusted using the technique described in a previous publication [18] . The trajectory in the coronal and sagittal planes were adjusted to place the entry point of the needle on the surface of the face approxi- The frame is mounted on the CT table with a skull in the head holder of the frame.…”

Objective: In this paper, a technique to place a probe at the trigeminal ganglion using a stereotactic frame and intraoperative computed tomography (CT) scans is described. Method: The procedure is performed on the CT table using a stereotactic frame. After the coordinates have been obtained and then adjusted, the target is probed using the frame. In this study, intraoperative scans were obtained to confirm the accuracy of probe placement. After successful stimulation studies, radiofrequency lesions were made. Thirty-two procedures were performed on 26 patients. Results: Twenty patients were free of pain at a follow-up which lasted a median of 30 months. There was no permanent complication from the procedure. Conclusions: The technique is straightforward, accurate and safe. It also enables the surgeon to obtain intraoperative confirmation of accurate probe placement on CT images.
