There's magnetoencephalography[1][2] which from what I could see offers a more direct route to measure brain activity.

MEG has much better temporal resolution than MR, but it’s spatial resolution is only marginally better (according to the below source, figure 6). However it doesn’t help that MR has a vast array of acquisition methods and techniques.

The below link is also interesting for its discussion of fMRI.
