  • Study explores image guidance based on MRI for spinal interstitial laser thermotherapy

    Researchers retrospectively reviewed 13 patients who underwent implantation of 47 laser catheters with image guidance based on intraoperative MRI during spinal laser interstitial thermotherapy. Investigators measured discrepancy in millimeters between trajectories of the predicted placement to the actual placement to assess the accuracy of the image guidance. The median changes in thickness of the epidural tumor and change in the epidural spinal cord classification were also assessed.
