Objective: This study was undertaken to point out restrictions and problems during surgery with the intraoperative MRI-system PoleStar N10.

Methods: Since March 2004 we operated 102 patients with the PoleStar N10. We reviewed all operations with a special concern for thedifficulties in positioning the patients, restrictions caused by the localisation of the tumor and we analyzed technical problems.

Results: In approximately 50% of all operations we found pitfalls worth reporting to other users or neurosurgeons reflecting on buying an intraoperative MRI-system. In only two cases did we have a total system crash and had to perform surgery without the PoleStar N10.

Conclusions: The PoleStar N10 is an appropriate tool to control the resection grade in tumor surgery. However, there are some restrictions making surgery with the PoleStar N10 very difficult.
