Interventional and intraoperative MRI approaches to deep brain stimulator implantation are relatively new, and in their purest form represent a distinct departure from traditional stereotactic techniques. They employ a novel means of stereotaxis based on regions of interest in the MR space and simple geometric principles, which eliminate the need for a stereotactic frame. This approach is appropriate for targets that are MR visible, and for whom the local anatomy and function are well characterized. It may also be appropriate for targets that do not have a well-described physiologic signature and for which clinical response to macrostimulation does not play a critical role. We will discuss the rationale and principles of this new technique as well as its advantages and disadvantages relative to awake, physiologically guided deep brain stimulation surgery.
用于深部脑刺激器植入的介入性和术中磁共振成像方法相对较新，其最纯粹的形式代表了与传统立体定向技术的明显不同。它们采用了一种基于磁共振空间中的感兴趣区域和简单几何原理的新型立体定向方法，从而无需使用立体定向框架。这种方法适用于在磁共振成像中可见的靶点，以及局部解剖结构和功能已得到充分表征的靶点。对于那些没有明确生理特征描述且宏观刺激的临床反应不起关键作用的靶点，这种方法也可能适用。我们将讨论这项新技术的基本原理及其相对于清醒状态下、生理引导的深部脑刺激手术的优缺点。
