At Ghent University Hospital patients go through an extensive work-up before the possibility of epilepsy surgery is discussed. All patients have long-term video-EEG-monitoring (usually 7 days), 3T MRI, FDG-PET and neuropsychological testing. In some patients additional investigations such as an ictal SPECT or intracarotid amobarbital test are done. Although there is long-standing expertise with EEG source localization within the clinical group, it was used infrequently due to the complexity of the source localization process and the time-investment that was required.

This has changed since we introduced Epilog PreOp and Epilog PreOp HD. Due to the ease-of-use and time-effectiveness of the Epilog service model, EEG and HD-EEG source localization is now performed for most of our patients that are in a preoperative work-up. With little extra time investment, we obtain additional information that can be used in the process of localizing the epileptogenic focus.

Geneva University Hospital

At the University Hospital of Geneva, the presurgical evaluation of refractory epilepsy patients contains a battery of clinical tests: structural MRI, video-EEG monitoring, interictal PET, ictal SPECT, neuropsychological examination, patient history and high-density EEG.
