Precontrast axial scans of 3D-FLAIR MR imaging in right inner ear of a 63-year-old man with right sudden sensorineural hearing loss with vertigo. Bright signals (arrows) are visible only in the right cochlea and vestibule at the level of the basal turn (A) and midturn (B) of the cochlea and vestibule, not in the left healthy cochlea and vestibule (open arrows).

Hearing improvement according to the Siegel criteria in the MRI+ and MRI− groups. CR indicates complete recovery; PR, partial recovery; SI, slight improvement; NR, no recovery.
- Fig 4.
Initial pretreatment and final posttreatment audiologic findings and the improvement of hearing (ΔPTA) in the MRI− and MRI+ groups according to the initial hearing loss. ΔPTA indicates the difference of mean pre- and posttreatment.
