Imaging of the Vestibule

摘要: Abstract PURPOSE: State-of-the-art imaging of the normal and pathologic vestibule. METHODS AND MATERIAL: This study is based on experience three French centers (Val de Grâce, Begin, Saint-Antoine hospitals) working with 1- 1.5-tesla magnetic resonance units high-resolution computed tomography, it includes a review literature. Computed tomography performed program, matrix 512 × 512, field view 9.6 cm, joined 1-mm section, overlapped sections every 0.5 mm, axial coronal sections, or reformatted images. High-resolution (matrix 384), 18 used fast T 2 -weighted sequences (sections 3 mm thick, constructive interference in steady state, gradient echo sequence three-dimensional Fourier transformation). A section 0.7 any direction obtained if necessary. Superimposition stereotactic technique by identification identical anatomic points sometimes used. RESULTS: We interest place diseases labyrinth internal auditory canal related to abnormal vestibular functions: inflammatory labyrinthitis, hemorrhages, sclerosing ossifying traumatism, malformations, perilymphatic fistulas, otosclerosis, tumors, cochleovestibular neuritis, hydrops endolymphatic system.
