Abstract
Three-dimensional fluid-attenuated inversion recovery (3D-FLAIR) MRI has recently been used to evaluate the pathology of the inner ear in cases of sensorineural hearing loss (SNHL). It is also possible by this method to detect the breakdown of the blood-labyrinth barrier in the affected ears. In this study, nine of twelve patients with sudden SNHL showed high signals in the affected ear on precontrast 3D-FLAIR. Two of these patients also showed gadolinium enhancement on 3D-FLAIR in the affected inner ear. Furthermore, the patient with acute [as different from “sudden”?] SNHL also showed gadolinium enhancement in the affected inner ear. This finding suggests a breakdown of the blood-labyrinth barrier at the time of the MRI. Further study is required to clarify the relationship between the 3D-FLAIR findings and the hearing prognosis. It is expected that 3D-FLAIR MRI would be useful for elucidating the pathologic condition in cases of SNHL.
