Mapping blood flow in the brain of athletes using an advanced form of ultrasound may make it easier to more accurately recognise concussions, a new study has revealed.
A new study from Robert Hamilton, Ph.D., co-founder of the L.A.-based software company Neural Analytics, points to using a transcranial Doppler device (TCD) to map blood flow in the brains of athletes as a way to more accurately and more immediately recognize and diagnose concussions.

Traditionally, concussions are diagnosed a good time after the impact event by MRI—and sometimes only in individuals with worsening or the most severe symptoms.
“There is growing evidence that concussions can change the blood flow in the brain,” said Hamilton. “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 TCD device.”
TCD uses ultrasound to map blood flow activity in the brain; but, the measurements it takes are usually not enough to diagnose a concussion by itself. The traditional technology only measures variables like the speed and pulse of blood flowing through arteries.
