A wide variety of tests can be used to determine if a patient has brain injury, and PET (positron emission tomography) is one of them. PET scanning technology relies on the fact that the brain stores glucose, and by tagging the glucose inside the brain with a radioactive tracer, the PET scanner can identify the areas of the brain where glucose is underutilized.
With PET scans being a useful imaging tool for brain injuries, experts now believe that it can be an indispensable tool in monitoring the brains of NFL players and athletes in other contact sports. Recently, scientists discovered that they can use PET scans to look for brain injury and repair markers in the brains of active and retired NFL players.
According to Jennifer Coughlin, assistant professor of psychiatry and behavioral sciences at Johns Hopkins University, the scientists believe that in PET scans, they have “a useful tool to monitor the brains of NFL players and athletes in other contact sports.”
