title: Intraoperative portable 0.12-tesla MRI in pediatric neurosurgery.
abstract: OBJECTIVE
  Intraoperative MRI (iMRI) is used mainly in the adult neurosurgical population. The main indications for iMRI usage are resection control and updated intraoperative navigation capabilities. In this paper we present our experience using this technique in children. Specific advantages of iMRI for this age group are discussed.
  
  
  RESULTS
  We retrospectively reviewed 31 pediatric neurosurgical procedures in which a portable iMRI system was used. The indications for iMRI usage were preoperative navigation, resection control during tumor removal, shunt placements, and needle biopsy. In 7 children the use of the iMRI changed the course of the surgical procedure. Operative morbidity and mortality were not increased with use of the iMRI.
  
  
  CONCLUSIONS
  iMRI systems have advantages for the pediatric neurosurgical population, including both real-time basic navigation and improved resection control.
