"Next generation" brain scanners, can they detect CTE?
I do not know the details of the innovation, but it's based on MEG. MEG is a complementary technique similar to EEG, sesitive to magnetic fields instead of electrical fields (hence the 'M' in place of the 'E'). It is used to read population brain activity in real time, and is less useful as a tool to assess structural changes. MEG is currently mainly used for research purpose, and I don't see this innovation changing that. CTE could manifest in longer conduction delays or disruption of communication, but given that MEG can only access certain areas of the brain, it is probably not going to be very useful in general. I can imagine it being useful for some very specific CTE cases.
