Neuronavigation in epilepsy surgery enables surgeons to accurately resect deep targets inside the brain, especially lesions that are unable to be visually differentiated from adjacent normal brain. The usefulness of visualizing subdural electrodes with postimplantation fusion CT/MRI was investigated. The use of platinum subdural electrodes made it possible to obtain postimplantation MRI. The postimplantation MRI and CT scans were fused on the surgical navigation system workstation to form three-dimensional (3D) images, and the epileptogenic regions were marked using the visualized electrodes. Immediately after a craniotomy was performed, the subdural electrodes were removed and the epileptogenic region was successfully resected using the neuronavigation guide. During neuronavigation-guided surgery to target deep brain epileptogenic lesions adjacent to eloquent areas, which are often invisible, we found visualization of the subdural electrodes with postimplantation fusion CT/MRI very useful.
神经导航在癫痫手术中使外科医生能够准确地切除大脑内部的深部目标，特别是那些无法从相邻的正常脑组织中视觉区分的病变。本研究旨在探讨术后融合 CT/MRI 显示植入物的效果。使用铂金电极可以进行术后 MRI 检查。术后 CT 和 MRI 扫描在手术导航系统工作站上融合，形成三维（3D）图像，并使用可视化电极标记致痫区。开颅后立即取出硬膜下电极，使用神经导航引导成功切除致痫区。在对位于语言区附近的深部脑致痫病变进行神经导航引导手术时，我们发现术后融合 CT/MRI 显示植入物非常有用，因为这些病变通常是不可见的。
