Abstract： Objective To review the clinical experience of intra-operative high-field magnetic resonance (MR) imaging suite with a movable magnet in dual room setting in neurosurgery.Methods From February to July 2009,120 patients in our department of neurosurgery were operated in a 1.5T intra-operative magnetic resonance imaging suite with a movable magnet,and a microscope-based funetional neuro-navigation system.Results 91 craniotomies and 29 transsphenoidal operations were performed.In 48(40.0%)patients,intra-operative MR imaging had revealed residual lesions and resulted in the change of surgical strategy(e.g.further resection of tumors).Eventually,98(81.7%)lesions were totally removed.Conclusions Intra-operative high-field MR imaging and functional neuro-navigation can be successfully integrated into standard neurosurgJcal workflow.It is helpful for maximizing the resection of lesions and minimizing the injury to neurological function.
