Abstract
MR using a susceptibility-weighted sequence and dynamic contrast enhancement with gadolinium demonstrated relative hyperperfusion of the right temporoparietal cortex in a patient in focal status epilepticus. A single-photon emission CT (SPECT) scan also demonstrated hyperperfusion of the right temporoparietal cortex. Perfusion MR, SPECT, and electroencephalogram normalized when the seizures ended.
摘要
使用磁化率加权序列和钆剂动态对比增强的磁共振成像（MR）显示，一名处于局灶性癫痫持续状态的患者右侧颞顶叶皮质存在相对高灌注。单光子发射计算机断层扫描（SPECT）也显示右侧颞顶叶皮质高灌注。癫痫发作结束后，灌注MR、SPECT和脑电图恢复正常。
