ABSTRACT
Objective To evaluate whether or not the 3.0T magnetic resonance (MR) scanner noise has adverse influence on neonatal hearing by using brainstem auditory evoked potentials(BAEP).Methods Forty-nine inpatients who received the MR examination were enrolled in this study from Aug.to Dec.2013,admitted to the Bayi Children's Hospital Affiliated to Beijing Military General Hospital.The Ⅰ,Ⅲ,Ⅴ wave latencies and the inter-peak intervals before and after the MR scan were compared by using SPSS 16.0 software.Results The BAEP results before and after MR examination respectively(1) The latencies wereleft ear Ⅰ wave (1.96 ± 0.22) ms vs (1.95 ± 0.30) ms,right ear Ⅰ wave (1.96 ± 0.22) ms vs (1.97 ± 0.27) ms,respectively; left ear Ⅲ wave (4.79 ± 0.23) ms vs (4.85 ± 0.28) ms,right earlllwave(4.78 ±0.24) ms vs (4.77 ±0.31) ms,respectively;left ear Ⅴ wave (7.10 ±0.24) ms vs (7.12 ±0.33) ms,right ear Ⅴ wave (6.76 ±0.32) ms vs (7.04 ±0.39) ms,respectively(allP >0.05).(2) The inter-peak intervals wereleft ear Ⅰ-Ⅲ inter-peak interval (2.83 ± 0.23) ms vs (2.86 ± 0.27) ms,right ear Ⅰ-Ⅲ inter-peak interval (2.82 ± 0.24) ms vs (2.80 ± 0.17) ms,respectively ; left ear Ⅲ-Ⅴ inter-peak interval (2.31 ±0.28) ms vs (2.31 ±0.29) ms,right ear Ⅲ-Ⅴ inter-peak interval (2.26 ±0.27) ms vs (2.26 ±0.23) ms,respectively;left ear Ⅰ-Ⅴ inter-peak interval (5.11 ±0.40) ms vs (5.13 ±0.35) ms,right ear Ⅰ-Ⅴ inter-peak interval (5.07 ± 0.39) ms vs (5.07 ± 0.36) ms,respectively(all P > 0.05).Conclusion The 3.0T MR may have no adverse influence on neonatal BAEP.
