We investigated the status of the cochleae in patients with vestibular schwannoma by evaluating the signal intensity of cochlear fluid on pre- and post-contrast enhanced thin section three-dimensional fluid attenuated inversion recovery (3D-FLAIR). Methods: Twenty-eight patients were retrospectively analyzed. Post-contrast images were obtained in 18 patients and 20 patients had the records of their pure-tone audiometry. Regions of interest of both cochleae (C) and of the medulla oblongata (M) were determined on 3D-FLAIR images by referring to 3D-heavily T2-weighted images on a workstation. The signal intensity ratio between C and M on the 3D-FLAIR images (CM ratio) was then evaluated. In addition, correlation between the CM ratio and the hearing level was also evaluated. Results: The CM ratio of the affected side was significantly higher than that of the unaffected side (p\u003c0.001). In the affected side, post-contrast signal elevation was observed (p\u003c0.005). In 13 patients (26 cochleae) who underwent both gadolinium injection and the pure-tone audiometry, the postcontrast CM ratio correlated with hearing level (p\u003c0.05). Conclusion: The results of present study suggest that alteration of cochlear fluid composition and increased permeability of the blood-labyrinthine barrier exist in the affected side in patients with vestibular schwannoma. Furthermore, although weak, positive correlation between post-contrast cochlear signal intensity on 3D-FLAIR and hearing level warrants further study to clarify the relationship between 3D-FLAIR findings and prognosis of hearing preservation surgery.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_12_description_5": {"attribute_name": "内容記述",
