摘要
目的 探究3.0T磁共振(MRI)扫描噪声对儿童耳蜗功能的影响.方法 前瞻性纳入2018年5月至11月在我院行头颅MRI检查的儿童72人,采用3M静音海绵耳塞与泡沫隔音头垫进行听力防护.应用免磁性麦克风和声级计对MRI序列的噪声水平(dBA)进行检测.采用畸变产物耳声发射(DPOAE)进行MRI检查前24 h与检查后30 min内2～7 kHz听功能(DPOAE幅值)检查.采用配对t检验或Wilcoxon符号秩检验分析MRI检查前后DPOAE振幅差异.结果 研究测得MRI平均噪声水平为(107.70±3.92)dBA.与MRI检查前相比,MRI检查后各频段DPOAE幅值(dB)变化较小,各年龄组振幅差值的变化范围为:0～1岁组左耳(-0.24～1.10),右耳(-0.24～0.74);2～5 岁组左耳(-0.07～0.59),右耳(-0.57～0.75);6～12 岁组左耳(-0.36～0.44),右耳(-0.30～0.57);且均未见有统计学差异(校正P＞0.05).结论 常规听力防护下,未观察到3.0T MRI噪声对儿童耳蜗功能的潜在影响.
Abstract
Objective To explore the effect of exposure to noise of 3.0T magnetic resonance imaging(MRI)on children's cochlear function.Methods We prospectively recruited 72 children who underwent cranial MRI examination at our hospital from May to November 2018;3M earplugs and sponge mats were used for hearing protection during MRI scanning.Noise level(dBA)of each MRI sequence was detected with a nonmagnetic microphone and a sound level meter.Distortion product otoacoustic emissions(DPOAE)test at 2-7 kHz was performed 24 hours before and 30 minutes after the MRI examination.Paired t-test or Wilcoxon signed-rank test was used to analyze differences in DPOAE amplitude before and after the MRI examination.Results The average noise level of MRI measured in the study was(107.7±3.92)dBA.Compared with that before the MRI examination,the DPOAE amplitude(dB)changed little after the MRI examination;the range of amplitude differences in each age group was as follows:left ear(-0.24-1.10)and right ear(-0.24-0.74)in the 0-1 year-old group;left ear(-0.07-0.59)and right ear(-0.57-0.75)in the 2-5 year-old group;left ear(-0.36-0.44)and right ear(-0.30-0.57)in the 6-12 year-old group.No statistically significant difference was found(correction P＞0.05).Conclusion No potential impact of 3.0T MRI noise on children's cochlear function was observed under routine hearing protection.
