Could a brain mri show a seizure?

See below: An MRI of the brain can not show a seizure, per se, but can show damaged areas where seizures may originate from. An interictal meg, ictal spect, and pet scans can be of benefit in some cases. An eeg, which looks at "brain waves", can show certain seizures as well. But a good history and exam are key to diagnosing epilepsy. A neurologist can help you with this. Hope that helps!
