EEG Electrical Source Imaging has been shown to be both Accurate and Useful.
Now with Persyst, it’s Practical.
Recent research shows that with the standard IFCN 25 EEG electrode array, ESI performs well within the same range of accuracy as other conventional neuroimaging modalities used in epilepsy presurgical evaluations, reliably localizing interictal spikes across epilepsy patient populations. ¹,²,³,⁴,⁵
One study demonstrated that, using a standardized methodology and clinician input, ESI accurately localized the epileptogenic zone in 78% of 41 consecutive surgical cases. This is the same range of accuracy as other neuroimaging modalities.¹
