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.Abstract Teaser
