Ultrasound technology may help pitchside concussion diagnosis

Research presented at the American Academy of Neurology’s 68th Annual Meeting (15 – 21st April, Vancouver, Canada) has profiled a new technology utilizing ultrasound to map blood flow within the brains of athletes to ultimately diagnose concussions more accurately. “There is growing evidence that concussions can change the blood flow in the brain. While such changes may be detected with MRI, we believe there may be a less expensive and portable way to measure these changes with a transcranial Doppler (TCD) device,” explained study author Robert Hamilton (Neural Analytics, CA, USA). TCD is traditionally used to measure variables such as...
