PET brain scans

David Geffen School of Medicine at UCLA

Normal brain scan (left), brain with suspected CTE (center) and brain with Alzheimer’s (right). More red and yellow indicates more abnormal brain proteins (tau and amyloid). 

The suspected CTE subject shows high levels of the FDDNP signal in the midbrain (red central area) and the amygdalae (smaller red areas located at 10 and 2 o’clock from the midbrain).  Also, in this more advanced case of suspected CTE, note the FDDNP signal (yellow and green) throughout the cortex, which is where most of the FDDNP signal is located in the Alzheimer’s case.
