The cochlear and the vestibular system play important roles in sound perception and maintaining the body equilibrium by sensing body movements and sending signals to the brain through mechanoelectric transduction. In order to use MRI for diagnosing inner ear diseases, improvement in the sensitivity of MRI and the development of an optimized special RF coil system and proper sequence protocol are needed. We presented preliminary results for visualization of the inner ear for the first time using only a customized RF coil and without the use of a contrast medium at 7 T.
