What is the recommended window for EEG monitoring related to seizures during PET scans?

The recommended window for EEG monitoring related to seizures during PET scans involves continuous observation before and during the seizure event. This approach is crucial because it allows for the detection of any seizure activity prior to the onset, which can be essential in understanding the patient's baseline neurological status. Additionally, monitoring during the seizure provides valuable data regarding the seizure's characteristics and its impact on the patient's brain activity, thereby aiding in accurate diagnosis and treatment planning.

Continuous EEG monitoring throughout this period ensures that any relevant changes in the brain's electrical activity are captured, allowing for a comprehensive assessment. The transient nature of seizures means that capturing them only after or before would miss crucial data on their dynamics and effects during the scan. Therefore, integrating EEG monitoring throughout the entire duration of the seizure—beginning before its onset and continuing through the event—ensures that medical professionals gather thorough and useful information related to the patient's neurological condition.
