摘　　要：目的探讨术中MRI对开颅手术中显微镜下导航漂移的纠正情况。方法回顾性分析接受术中MRI结合显微镜下导航手术治疗的113例患者的临床资料。仰卧位手术76例,俯卧位37例。术中显微镜下导航,出现导航漂移者以术中MRI加以更新和纠正。结果100例患者导航或经纠正后手术导航精确,13例术中出现导航偏差,其中3例术后发现导航准确,10例导航失败。结论正确使用术中MRI可有效纠正导航漂移,提高手术导航的精确度。Objective To explore the application of intraoperative MRI to correcting the drifting of the neuronavigation under a microscope when intracranial microsurgery is performed.Methods The clinical data of 113 patients with intracraional lesions whou nderwent intracranial microsurgery assisted with intraoperative MRI combined with neuronavigation were analyzed retrospectively.Of 113 patients,76 kept supine position,and 37 prone position during the microsurgery.The drifting during the neuronavigation wasc orrected by the image acquired from the intraoperative MR rescanning.Results The accuracy of the neuronavigation was attained in 76 patients and the drifting during the neuronavigation was corrected by intraoperative MRI in 27 patients.The neuronavigation was nots uccessful in 10 patients.Conclusions The use of intraoperative MRI may effectively correct the drifting of the navigation,and increaset he accuracy of the neuronavigation during the microsurgery for the intracranial lesions.
