Abstract：
UNASSIGNED: To investigate the diagnostic value of three-dimensional fluid-attenuated inversion recovery (3D-FLAIR) MRI in children with sudden deafness caused by inner ear hemorrhage.
UNASSIGNED: The diagnostic efficacies of three different MRI sequences in the examination of the inner ear for 32 children with sudden deafness were compared. Hearing examination results and 3-month follow-up outcomes were analyzed.
UNASSIGNED: The age of 32 children with sudden deafness ranged from 5 to 18 years. MRI was performed from 1 to 18 days after onset. Six cases of sudden deafness caused by inner ear hemorrhage were finally diagnosed clinically. For different MRI sequences, the 3D-FLAIR sequence detected five positive cases; the conventional T1-weighted image sequence also detected five positive cases; but the conventional T2-weighted image sequence only detected three positive cases. The sensitivity and specificity of the 3D-FLAIR sequence in the diagnosis of inner ear hemorrhage were 83.3% (5/6) and 96.2% (25/26), respectively, and the area under the curve value of the receiver operating characteristic curve was 0.897. In the hemorrhage group, all six cases had extremely severe sensorineural hearing loss, and the hearing recovery was ineffective after 3 months of follow-up. The degree of hearing impairment, 3-month short-term treatment efficacy, and 3D-FLAIR MRI in the diagnosis of inner ear hemorrhage between hemorrhage group and non-hemorrhage group were statistically significant (p=0.043, p=0.000, p=0.000).
UNASSIGNED: 3D-FLAIR MRI is helpful for the diagnosis of inner ear hemorrhage in children with sudden deafness. Besides, short-term treatment indicates poor effects on children with severe hearing impairment.

摘要：
UNASSIGNED：探讨三维液体衰减倒置恢复（3D-FLAIR）MRI对儿童内耳出血引起的突发性耳聋的诊断价值。
UNASSIGNED：比较了三种不同的MRI序列在内耳检查中对32例突发性耳聋儿童的诊断效果。分析听力检查结果和3个月的随访结果。
未经评估：32岁的突发性耳聋儿童的年龄为5至18岁。发病后1至18天进行MRI检查。6例因内耳出血引起的突发性耳聋最终得到临床诊断。对于不同的MRI序列,3D-FLAIR序列检测到5例阳性病例；常规T1加权图像序列也检测到5例阳性病例；但常规T2加权图像序列仅检测到3例阳性病例。3D-FLAIR序列诊断内耳出血的敏感度和特异度分别为83.3%(5/6)和96.2%(25/26),分别,受试者工作特性曲线的曲线下面积值为0.897。在出血组中，所有六例都有非常严重的感觉神经性听力损失，随访3个月后听力恢复无效。听力损伤的程度,3个月的短期治疗效果，3D-FLAIRMRI对内耳出血的诊断在出血组和非出血组之间有统计学意义(p=0.043,p=0.000,p=0.000)。
UNASSIGNED：3D-FLAIRMRI有助于突发性耳聋儿童内耳出血的诊断。此外,短期治疗表明对严重听力障碍儿童的影响较差。
