Summary

A first-in-class PET imaging approach can accurately detect a biomarker for chronic traumatic encephalopathy (CTE), a devastating neurodegenerative disease associated with repeated head impact. Rather than waiting until after death for a definitive diagnosis, this imaging biomarker has the potential to diagnose patients while they are still alive and could play a critical role in supporting clinical trials to develop CTE treatments. This research was presented at the Society of Nuclear Medicine and Molecular Imaging 2026 Annual Meeting.
