Blood Test and PET Scan Offer New Ways to Detect Brain Injuries

Scientists in Australia have developed a blood test that measures concussion‑related biomarkers, providing an objective tool to identify mild traumatic brain injury in older adults and improve emergency triage and treatment decisions.

Separately, a novel PET‑scan tracer, ¹⁸F‑OXD‑2314, has been described as a "first‑in‑class imaging tool" capable of visualising the tau protein patterns that define chronic traumatic encephalopathy (CTE) in living patients, opening the path to earlier diagnosis and more precise evaluation of potential therapies.
