The best way to explain the
advantages of Ultra-High Filed
MRI is to define its level of detail.
For a traditional MRI scan of the
brain, a “voxel” on the scan con-
tains about 100,000 brain cells. A
voxel is simply a cubic unit of the
image similar to a pixel on your
smartphone. For Ultra-High Fast
MRI scans, each voxel contains a
much smaller number of cells to
view. In fact, the estimate is that
these voxels only contain a few
thousand cells. The more refined

the mRi neuroimaging has
been around for some time, but
its clinical use only took off in the
early 1980s. Only a few know, but
research used Ultra-High Filed
MRIs beginning 1998. In 2015,
nearly 40 million MRI scans were
