High-Resolution Scans Combined with Analysis to Help Detect Concussions

Mild Traumatic Brain Injuries (MTBI), a frequent injury in American football players, are also not easily detected by conventional imaging scans.

The researchers from the Simon Fraser University (SFU; Burnaby, BC, Canada) took MEG imaging scans of 41 men between 20 and 44 years old, half of who had a diagnosis of concussion in the three months prior to the scan, and found observable changes in communication between different areas of the patient’s brains. MEG functional neuroimaging is an imaging technique used for mapping brain activity that currently uses extremely sensitive magnetometers called Superconducting Quantum Interference Devices (SQUIDs).

One of the researchers, Vasily Vakorin, from the Behavioral and Cognitive Neuroscience Institute at the SFU, said, "Changes in communication between brain areas, as detected by MEG, allowed us to detect concussion from individual scans, in situations where MRI or CT failed."
