Localization of Brain Injuries Using Cranial Electromagnetic Fields.
This prospective clinical study evaluated a noninvasive portable helmet system to record and localize brain EMF activity in adults with atraumatic brain injury or TBI, including image-negative concussion. Ten patients were enrolled, and abnormal EMF activity was reported to correlate with neurological deficits, CT findings, or both. The authors conclude the approach is feasible and may be useful for real-time localization and monitoring, though details on accuracy and quantitative performance are not provided in the abstract.
Key points
- The study prospectively enrolled adults with atraumatic brain injury or TBI, including concussions with negative imaging.
- A helmet with 20 sensor stimulators was used to record baseline brain EMF activity and compare adjacent/opposing sensors.
- EMF signals were analyzed using fast Fourier transformation to identify normal versus abnormal patterns.
- Abnormal EMF activity was reported to correlate with neurological exam deficits and/or CT lesions.
- Seven of ten patients had no intracranial abnormalities on imaging, yet abnormal EMF activity was still reported.
- The authors describe the device as feasible for real-time recording and localization in this small cohort.
