title: Use of an ultra-low field intraoperative MRI system for pediatric brain tumor cases: initial experience with 'PoleStar N20'.
abstract: OBJECTIVE
  Use of intraoperative MRI (iMRI) is the highest contemporary supportive means for brain tumor surgery. In this article we describe the issues related to iMRI use in pediatric cranial operations.
  
  
  METHODS
  Pediatric cases operated with the aid of Polestar N20 iMRI system are defined and the pros and cons of the system are emphasized.
  
  
  RESULTS
  Patient positioning is easier and the obtained images are better in pediatric cases, particularly for posterior fossa tumors.
  
  
  CONCLUSIONS
  iMRI should be used in all pediatric brain tumor operations when possible.
