Ictal and interictal single-photon emission CT (SPECT) play an increasingly important role in the surgical evaluation of patients with epilepsy. We present a method of coregistration of MR, SPECT, and CT images to correlate structural data (MR imaging), blood flow changes (SPECT), and location of subdural electrodes (CT) for patients undergoing image-guided surgical treatment of epilepsy. MR-SPECT root mean square (rms) mismatch distances were 2.1 to 2.5 mm, and MR-CT rms mismatch distances were 1.0 to 4.5 mm. Coregistration assisted in image-guided placement of subdural electrodes and in surgical resection of the suspected epileptogenic focus.
发作期和发作间期单光子发射计算机断层扫描（SPECT）在癫痫患者的手术评估中发挥着越来越重要的作用。我们提出了一种用于磁共振成像（MR）、SPECT和CT图像配准的方法，以关联接受癫痫图像引导手术治疗患者的结构数据（MR成像）、血流变化（SPECT）和硬膜下电极位置（CT）。MR-SPECT均方根（rms）不匹配距离为2.1至2.5毫米，MR-CT rms不匹配距离为1.0至4.5毫米。配准有助于硬膜下电极的图像引导放置以及疑似致痫灶的手术切除。
