The purpose of this study was to evaluate the usefulness of the combination of an advanced high\u2010resolution T2\u2010weighted sequence with a surface coil in a 3\u2010Tesla magnetic resonance imaging scanner in cases of suspected cochlear nerve aplasia.<\/jats:p><\/jats:sec><jats:sec><jats:title>Study Design<\/jats:title><jats:p>Prospective study.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Seven patients with cochlear nerve hypoplasia or aplasia were prospectively examined using a high\u2010resolution three\u2010dimensional variable flip\u2010angle turbo spin\u2010echo sequence using a surface coil, and the images were compared with the same sequence in standard resolution using a standard head coil.
