MRI anatomical study of normal inner ear

To study MRI technique of membranous labyrinth of normal inner ear, and evaluate the ability of MRI on displaying these structures. Methods MRI scanning were performed with 3D EASE - Heavily T2WI sequence on 30 normal subjects and volunteers, then maximum intensity projection (MIP) technique was conducted in multi - angle views, and membranous labyrinth of inner ear was observed and evaluated. Results The tiny structures of membranous labyrinth of inner ears, acoustic and facial nerves were well demonstrated. Conclusion The normal structures of membranous labyrinth, acoustic nerve and facial nerve can be displayed on 3D FASE - Heavily T2WI sequence in multiple directions. It is valuable in diagnosing the lesions of these regions.
