The use of MRI, MRSI, PET, and SPECT scanning for preoperative evaluation of patients with epilepsy is reviewed. MRI provides the best anatomic detail and contains prognostic information. PET provides useful information in some patients for whom MRI findings are absent or contradictory. Interictal SPECT scanning lacks sufficient specificity to be of use in the preoperative evaluation of refractory patients, whereas ictal SPECT appears to be useful in temporal and extratemporal lobe epilepsy. The new technique of MRSI is described.
对使用MRI、MRSI、PET和SPECT扫描进行癫痫患者术前评估的情况进行了综述。MRI提供了最佳的解剖细节并包含预后信息。PET为一些MRI检查结果缺失或相互矛盾的患者提供了有用信息。发作间期SPECT扫描缺乏足够的特异性，无法用于难治性患者的术前评估，而发作期SPECT似乎对颞叶和颞叶外癫痫有用。文中描述了MRSI这项新技术。
