High Density EEG Neuroimaging
Patient friendly procedure
Not only has HD EEG been shown to yield clinically important information, it is also more cost effective and can be used with a broader range of patients, compared to other methods. High Density EEG can be used at the bedside, is tolerant of patient movement during the procedure, and requires no radiation or dedicated procedure room. EGI's HD EEG system is especially patient friendly, requiring no scalp abrasion, glues, restraints, or sedation.
A valuable tool in presurgical planning
For patients suffering from focal epilepsy that cannot be controlled by medication, surgery to resect the epileptic zone can offer relief from symptoms, resulting in a higher quality of life. A comprehensive presurgical evaluation is critical to a positive surgical outcome.

High channel count EEG recommended as a quality standard for presurgical epilepsy workup. The working group on presurgical epilepsy diagnosis and operative epilepsy treatment has published their guidelines for quality standards for Austria, Germany, and Switzerland. The standards include video EEG with at least 64 channels and at least two other advanced imaging methods, such as 64-256 channel EEG with source imaging. Access the paper. |
High Density EEG (HD EEG) with 128 or 256 electrodes is attracting interest as an important tool for use in epilepsy presurgical planning. Recent large-scale studies indicate that HD EEG compares favorably to other noninvasive methods, such as conventional EEG, PET (positron emission tomography), ictal SPECT (single-photon emission computed tomography), and MRI (magnetic resonance imaging), for identifying the irritative zone in focal epilepsy (see for example Brodbeck et al., 2011). Used with specialized software, such as GeoSource 2.0, HD EEG data can be used for visualization of human brain function.
