Hospital MRI scanners, using 3 Tesla magnets, provide poor spatial resolution in brain imaging. More recent 7T MRIs are better but used mainly in the rare research lab. Scientists have now supercharged the standard 7T scanner to improve the resolution by nearly a factor of 10 -- a 50-times improvement over standard 3T MRIs. The NexGen 7T can track signals through the brain and perhaps tie functional changes to brain maladies.
