摘要目的 回顾总结移动磁体高场强术中磁共振成像(iMRI)系统在神经外科的临床应用经验.方法 自2009年2月至7月,共有120例患者接受iMRI辅助下的手术.结果 91例行开颅手术和29例经蝶窦手术.48例(40.0%)术中使用iMRI发现残留病灶并改变了手术策略,扩大了切除范围.病变全切率81.7%.结论 移动磁体高场强iMRI和功能神经导航系统能够被很好地整合进神经外科手术流程,对改进手术策略,最大化地切除病灶和最大程度地保留神经功能很有帮助.

abstractsObjective 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.
