“This technique produced detailed images of the dynamics of neural signals in our target region that could not be seen with other non-invasive techniques like fMRI. We produced a level of detail approaching electrophysiology, but with a far less invasive procedure."

This seems like it might be useful for studying how ME affects muscle function. Maybe it can also reveal other neural abnormalities in ME. Even if it's only "just as good as fMRI" but much cheaper, it would be helpful for research.

It images "high-resolution blood flow dynamics in the brain", and since there are questions about ME affecting blood flow, this might be helpful for that.
