title: Application of ictal brain SPECT for differentiating epileptic from nonepileptic seizures.
abstract: The authors report 2 clinical cases that illustrate the difficulties with video-monitored EEG and the advantages of brain SPECT in differential diagnosis of true epileptic seizures and nonepileptic seizures. Injection of [99mTc]HMPAO at the time of the ictal event provides a means to obtain a SPECT image postictally for comparison with interictal examinations so that an epileptic or nonepileptic focus may be localized.
