经颅磁刺激(TMS)是一种无创刺激大脑皮层的方法,在精神病学中有应用,如治疗抑郁症和焦虑症。尽管存在许多使用图8线圈的TMS靶向方法,但许多方法没有考虑到解剖学上的个体差异,或者不能在靶点上推广。该方案结合了功能磁共振成像(FMRI)和迭代电场(E-field)建模,以一种通用的方法来针对特定对象的TMS目标,能够优化刺激位置和TMS线圈方向。为了应用该协议,用户应该(I)操作地定义感兴趣区域(ROI),(Ii)从结构MRI数据生成头部模型,(Iii)对功能MRI数据进行预处理,(Iv)识别ROI内的单个受试者刺激部位,以及(Iv)进行电场建模以识别最佳线圈方向。与标准的靶向方法相比,这种方法显示了(I)在不同受试者之间刺激部位的可变性降低,(Ii)头皮到皮质靶点的距离减少,以及(Iii)最佳线圈方向的可变性减少。执行这一方案需要在结构和功能磁共振成像处理方面的中级技能。该方案耗时约24小时完成,并演示了如何将受限的fMRI靶向与迭代电场建模相结合,作为一种通用方法来优化TMS线圈的位置及其取向。
Transcranial magnetic stimulation (TMS) is a noninvasive method to stimulate the cerebral cortex that has applications in psychiatry, such as in the treatment of depression and anxiety. Although many TMS targeting methods that use figure-8 coils exist, many do not account for individual differences in anatomy or are not generalizable across target sites. This protocol combines functional magnetic resonance imaging (fMRI) and iterative electric-field (E-field) modeling in a generalized approach to subject-specific TMS targeting that is capable of optimizing the stimulation site and TMS coil orientation. To apply this protocol, the user should (i) operationally define a region of interest (ROI), (ii) generate the head model from the structural MRI data, (iii) preprocess the functional MRI data, (iv) identify the single-subject stimulation site within the ROI, and (iv) conduct E-field modeling to identify the optimal coil orientation. In comparison with standard targeting methods, this approach demonstrates (i) reduced variability in the stimulation site across subjects, (ii) reduced scalp-to-cortical-target distance, and (iii) reduced variability in optimal coil orientation. Execution of this protocol requires intermediate-level skills in structural and functional MRI processing. This protocol takes ~24 h to complete and demonstrates how constrained fMRI targeting combined with iterative E-field modeling can be used as a general method to optimize both the TMS coil site and its orientation.
