Abstract:
Seizures (including postictal state) account for about 38% of stroke mimics, which are easily confused with acute ischemic cerebrovascular events. Electroencephalogram, with a low interictal positive rate, has limitations in early diagnosis of epileptic seizures because it is usually unavailable in the emergency room. In acute settings, CT perfusion imaging is economical and has a short examination time. It is widely used for early screening and evaluation of suspected stroke. Seizures are accompanied by perfusion changes and have certain characteristics. CT perfusion patterns in different periods, especially for focal hyperperfusion, can distinguish stroke-like seizures from cerebrovascular events at an early stage. It helps to make a clear diagnosis and appropriate clinical decisions, leading to improve patients′ prognosis.
