  • Title: Interventional MRI-guided frameless stereotaxy in pediatric patients.
    Author: Vitaz TW, Hushek SG, Shields CB, Moriarty TM.
    Journal: Stereotact Funct Neurosurg; 2002; 79(3-4):182-90. PubMed ID: 12890976.
    Abstract:
    INTRODUCTION: We prospectively reviewed our experience with intraoperative MRI (iMRI)-guided stereotactic procedures in pediatric patients. METHODS: All procedures were performed within the magnet bore of the General Electric Signa SP MRI system, which allows for either continuous real-time or periodic imaging. The internal optical tracking system was used to plan and monitor target localization and instrument trajectory. RESULTS: Fifteen patients underwent 16 frameless stereotactic procedures, consisting of 4 tumor biopsies and 12 cyst aspirations and stereotactic catheter placements (average age 6 years, range 6 weeks to 18 years). There were no hemorrhagic, neurologic or infectious complications. CONCLUSION: iMRI is an important component in expanding the horizon of minimally invasive neurosurgery for pediatric patients. Thus far, we have found this technology to be safe, reliable and extremely useful for frameless stereotactic procedures.
