UC Berkeley researchers have developed a device that uses wireless signals to provide real-time, non-invasive diagnoses of brain swelling or bleeding. The device’s diagnoses for the brain trauma patients in the study matched the results obtained from conventional computerized tomography (CT) scans. Because fluid conducts electricity differently than brain tissue, it is possible to measure changes in electromagnetic properties. The tests also revealed some insights into the aging brain. With increased age, the average electromagnetic transmission signature of a normal human brain changes and approaches that of younger patients with a severe medical condition of hematoma in the brain. For brain hematomas, internal bleeding causes the buildup of blood in certain regions of the brain. For brain edemas, on the other hand, swelling results from an increase in fluid in the tissue.
