脑组织存在功能的“可塑性”,在颅脑肿瘤的治疗中,应该以动态的眼光分析肿瘤的发展过程和脑组织功能区的再分布。目前术前常用的技术有PET、fMRI、EEG、MEG、DTI等,这些技术有助于手术方案的制定,但是不能将手术必须保留的功能区和其附近的潜在“代偿区”分辨出来。术中可以采用导航、电生理定位及皮层电刺激,实时确定皮层和皮层下的功能区域,辅助确定切除范围。将目前各种技术灵活组合,互补优缺,才能取得更好的效果。
Brain tissue has the function of “plasticity”, in the treatment of brain tumors, the dynamic development of the tumor should be analyzed and redistribution of functional areas of brain tissue. At present, PET, fMRI, EEG, MEG, DTI and so on are commonly used before surgery. These techniques are helpful for the development of surgical plans, but they can not distinguish the functional areas that the operation must retain and the potential “compensatory zones” in the vicinity. Intraoperative navigation, electrophysiological localization and cortical electrical stimulation can be used to determine the functional areas under the cortex and cortex in real time to help determine the extent of resection. The current flexible combination of various technologies, complementary advantages and disadvantages, in order to achieve better results.
