用途：本研究的目的是评估是否前庭内淋巴空间的体积与听力损失的程度使用重T2加权快速成像采用稳态采集与周期相位FIESTA-C）MRI.Materials和方法：共23例前庭神经鞘瘤，诊断为典型的图像表现，谁接受FIESTA-C MRI。有13名女性和10名男性，平均年龄为63.5 ± 9.3 SD（年龄范围：49-88岁）。两名放射科医生独立评价椭圆囊和球囊的体积。结果：平均囊状、椭圆囊和肿瘤体积分别为3.17 ± 1.1（SD）mm（3），14.55 ± 5（SD）mm（3）;范围：1.45-5.7 mm（3），14.55 ± 5（SD）mm（3）;范围：1.45-5.7 mm（3），14.55 ± 5（SD）mm（3）; 6.6-23.9 mm（3））和17.4 +/- 5.5 SD）mm（3）;范围：8.3-25.4 mm（3））。椭圆囊体积与听力损失程度之间存在中度相关性，如纯音平均rho = 0.5; P = 0.015）和语音识别阈值rho = 0.58; P = 0.004）。囊状和肿瘤体积和听力损失的程度之间没有显着的相关性。结论：阻塞性前庭神经鞘瘤患者的椭圆囊的体积中度相关的听力损失的程度。(c)2019法国放射学会。由Elsevier Masson SAS出版。All rights reserved.
Purpose: The purpose of this study was to assess whether the volume of the vestibular endolymphatic space correlates with the degree of hearing loss using heavily T2-weighted fast imaging employing steady-state acquisition with cycle phase FIESTA-C) MRI.Materials and methods: A total of 23 patients with vestibular schwannoma, as diagnosed on typical image findings, who underwent FIESTA-C MRI were included. There were 13 women and 10 men with a mean age of 63.5 +/- 9.3 SD) years range: 49-88 years). Two radiologists independently evaluated the volume of the utricle and saccule. Correlation between tumor volume, vestibular endolymphatic space volume and degree of hearing loss - as evaluated with the levels of pure-tone average and speech recognition threshold - were searched for.Results: The mean saccular, utricular and tumor volumes were 3.17 +/- 1.1 SD) mm(3) range: 1.45-5.7 mm(3)), 14.55 +/- 5 SD) mm(3); range: 6.6-23.9 mm(3)) and 17.4 +/- 5.5 SD) mm(3); range: 8.3-25.4 mm(3)), respectively. There was a moderate correlation between the volume of the utricle and the degree of hearing loss as evaluated with the levels of pure-tone average rho = 0.5; P = 0.015) and speech recognition threshold rho = 0.58; P = 0.004). There were no significant correlations between saccular and tumor volumes and the degree of hearing loss.Conclusion: The volume of the utricle in patients with obstructive vestibular schwannoma moderately correlates with the degree of hearing loss.
