Use of an ultra-low field intraoperative mri system for pediatric brain tumor cases: Initial experience with 'polestar N20

Abstract

Aim: 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. Material and 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. Conclusion: iMRI should be used in all pediatric brain tumor operations when possible.
