[MR imaging of the vestibular aqueduct in normal volunteers and patients with Menière's disease--a preliminary report].
In this paper we attempted MR visualization of the vestibular aqueduct (VA) with a surface coil. Sagittal plane was most preferable from the result of preliminary study using a dry temporal bone. In all of ten normal volunteers, VAs were visualized well. In none of them, proton-density weighted spin-echo (SE) images were inferior to both T1- and T2-weighted SE image. In four of eight patients with Menière's disease, VAs were not visualized due to obstruction of VA, although in all of ten non-Menière's patients with hearing loss or vertigo, VAs were well visualized. Although further investigation is needed, MR imaging of VA including both its content and surrounding bony structure would give important information to manage the patients with either Menière's disease or other disorders of internal ears.
