          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
        performed on patients in the U.S.
        alone.
          Neurologists and physicians
        consider the mRi as the most im-
        portant medical development in
        the last quarter century. it’s there-
        fore not surprising that MRI neu-
        roimaging continues to advance,
