From the above link:

The specialized applications of 3T MRI offer clinical benefits in several areas. Here's an overview:

Neurology
...•reveals the brain's fiber tracts, showing how the brain is "wired." Tractography, the 3-D representation of this data, illustrates the location of fiber tracts and how they connect in the brain. In cases of traumatic brain injury, stroke and seizures, DTI can help assess levels of cognitive deficit and brain damage.

this is happening now and 3 tesla should be relatively available in a few years. Being able to guide therapy should be a big step
