Accurate and Inexpensive Device Used to Diagnose TBI
Currently there are two accepted techniques to determine whether a traumatic brain injury has been incurred or not. One is a functional magnetic resonance imaging (MRI) and the other is the CT scan. Both are expensive. A new technology will be introduced by two Japanese scientists at the University of Houston that promises to deliver more comprehensive and accurate diagnosis at a fraction of the cost. The technology combines high-density electroencephalography (EEG) and near-infrared spectroscopy (NIRS) to detect cerebral blood flow. Combining the EEG and NIRS will study both electrical and metabolic activities at the same time to improve patient benefits. The device fits on a patient’s head and the configuration of fiber optics and special electrodes sends light into the brain. The light scatters as it travels through the layers of the brain tissue and is then reflected out and measured by a set of sensors.
