title: Intraoperative MRI for pediatric tumor management.
abstract: The emergence of intraoperative MRI has opened new doors for the surgical treatment of pediatric disorders. This technology will hopefully not only improve the surgeon's ability to obtain complete tumor resections with minimal damage to surrounding structures, but also allows surgeons to perform various procedures via less invasive measures. We performed a total of 38 procedures in 36 children in our intraoperative MRI system (GE Signa SP, open configuration). All procedures were performed within the magnet bore, which allows for either continuous real-time or periodic imaging. Procedures included craniotomy for tumor resection, open biopsy, stereotactic biopsy or catheter placement into a tumor-related cyst. There were no infectious, hemorrhagic or neurological complications. Intraoperative MRI is an useful tool for the management of pediatric neurosurgical disorders. Intraoperative imaging not only helps surgeons navigate through eloquent areas of the brain, but also ensures the maximal possible tumor resection or confirms adequate catheter placement prior to skin closure. The impact of this technology on long term survival is yet to be determined.
