Electrical Impedance Tomography of Epilepsy
Conditions: Epilepsy
Sex: All
Ages: 18 Years – N/A
Healthy volunteers: No
Enrollment: 42
Sponsor: University College, London
Location: EEG telemetry unit Neurophysiology National Hospital for Neurology and Neurosurgery London
Summary
The purpose of this study is to determine if Electrical Impedance Tomography (EIT) can produce reproducible and accurate images in people with epilepsy compared to existing standards such as MRI, CT or EEG.
Electrical Impedance Tomography is a relatively new medical imaging method, which has the potential to provide novel images of brain function. It is fast, portable, safe and inexpensive, but currently has a relatively poor spatial resolution. It produces images of the internal electrical impedance of a subject with epilepsy using rings of ECG like electrodes on the skin, intracranial electrode mats or deep electrodes implemented surgically as part of clinical assessment. EIT recording will take place in parallel with the routine recording on the ward. Following completion of the recording, the EIT images will subsequently be analysed and compared to other imaging data for accuracy.
