Summary

This study tests whether Electrical Impedance Tomography (EIT) can produce accurate images of brain activity in people with epilepsy. EIT uses harmless electrical signals through electrodes on the scalp or brain to create images, and is compared to standard methods like MRI and EEG. The goal is to see if EIT can offer a fast, portable, and safe alternative for imaging seizures.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Electrical Impedance Tomography (EIT) device
What this could lead to: If successful, EIT could become a fast, portable, and safe way to image brain activity during seizures, helping doctors better understand epilepsy.
What could go wrong: This is an early-stage study with only 42 participants, focused on accuracy rather than treatment. EIT currently has poor image resolution, so it may not outperform existing methods like MRI.
