Ultra high resolution MRI capable of resolving the
cochlear internal structures has been performed in small
bore MRI scanners with higher field strength(>4.7T) and
gradient performance. We hypothesize that improved
images of the cochlear anatomy may also be obtained on
high field human MRI scanners that have increased
gradient performance and performed high resolution
rodent cochlea imaging using an insert gradient array
simultaneously with the whole body gradients of our 3T
clinical MRI scanner. The use of composite gradients
will allow for higher spatial resolution cochlear
imaging while maintaining acceptable SNR and scan
duration and decreasing artifact.
