摘要目的：三维液体衰减反转恢复磁共振成像已被用于检测内耳液成分的变化。本研究旨在探讨突发性感音神经性耳聋患者的听力水平与对比前后三维液体衰减反转恢复磁共振成像信号强度之间的关系。方法：对18例突发性感音神经性听力损失患者进行了三维液体衰减反转恢复磁共振成像：12例轻中度感音神经性听力损失患者（基线听力水平为60 dB或更低）和6例重度至极重度感音神经性听力损失患者（基线听力水平超过60 dB）。结果如下：在6例重度至极重度感音神经性听力损失患者中，有2例（33%）观察到内耳高强度信号，但在轻度至中度感音神经性听力损失患者中未观察到（中p检验，p = 0.049）。这些信号在感音神经性听力损失发作后6或18天在磁共振成像扫描上观察到。结论：结果表明，三维液体衰减反转恢复磁共振成像是不是一个有用的工具，检测轻度感音神经性听力损失患者的内耳异常。
Abstract Objective: Three-dimensional fluid-attenuated inversion recovery magnetic resonance imaging has been used to detect alterations in the composition of inner-ear fluid. This study investigated the association between hearing level and the signal intensity of pre- and post-contrast three-dimensional fluid-attenuated inversion recovery magnetic resonance imaging in patients with sudden-onset sensorineural hearing loss. Method: Three-dimensional fluid-attenuated inversion recovery magnetic resonance imaging was performed in 18 patients with sudden-onset sensorineural hearing loss: 12 patients with mild-to-moderate sensorineural hearing loss (baseline hearing levels of 60 dB or less) and 6 patients with severe-to-profound sensorineural hearing loss (baseline hearing levels of more than 60 dB). Results: High-intensity signals in the inner ear were observed in two of the six patients (33 per cent) with severe-to-profound sensorineural hearing loss, but not in those with mild-to-moderate sensorineural hearing loss (mid-p test, p = 0.049). These signals were observed on magnetic resonance imaging scans 6 or 18 days after sensorineural hearing loss onset. Conclusion: The results indicate that three-dimensional fluid-attenuated inversion recovery magnetic resonance imaging is not a useful tool for detecting inner-ear abnormalities in patients with mild sensorineural hearing loss.
