传统神经导航技术能提高手术疗效,但对涉及大脑功能区的肿瘤效果并不理想。如何在手术时对功能区肿瘤进行精确定位,有效识别肿瘤附近的功能皮质及传导束,在最大程度切除肿瘤的同时尽可能保全病人的神经功能显得尤其重要。术中神经电生理监测技术(IOM)一直被视为定位功能区皮质及其传导纤维的金标准,而功能磁共振(fMRI)、弥散张量成像(DTI)及纤维示踪技术(FT)能无创显示大脑功能皮质及传导束的功能状态,近年来也备受关注。在涉及功能区肿瘤切除手术中,传统导航结合IOM、fMRI及DTI,并运用术中磁共振(iMRI)纠正术中脑移位成为近年来的研究方向。
Traditional neuro-navigation technique can improve the curative effect, but it does not work well for tumors involving brain functional areas. How to accurately locate the tumor in the functional area at the time of surgery and effectively identify the functional cortex and the conductive bundles near the tumor are particularly important in maximizing the removal of the tumor while preserving the neurological function of the patient as much as possible. Intraoperative electrophysiological monitoring technique (IOM) has long been regarded as the gold standard for locating the functional cortex and its conductive fibers, and functional magnetic resonance imaging (fMRI), diffusion tensor imaging (DTI), and fiber tracing techniques Noninvasive display of brain functional cortical and conductive bundles of functional status, in recent years has also attracted much attention. In the functional area tumor resection, traditional navigation combined with IOM, fMRI and DTI, and the use of intraoperative magnetic resonance imaging (iMRI) to correct intraoperative brain shift has become the research direction in recent years.
