PET Scan May Reveal C.T.E. Signs, Study Says

For years, researchers have had to use tissue obtained posthumously to diagnose chronic traumatic encephalopathy, or C.T.E., the degenerative brain disease that has bedeviled athletes, soldiers and others who have sustained repeated head hits and concussions.

But a study published in The American Journal of Geriatric Psychiatry on Tuesday suggests that PET scans could one day be used to diagnose the disease in living patients.
