Loud acoustic noise generated from magnetic resonance (MR) imaging remains the great concern for neonatal exams. This study therefore aims to clarify whether this noise would cause the hearing loss to neonates who underwent MRI exam by auditory brainstem response (ABR). Results indicated that there was no significant difference in all the six ABR indices (waves I, III, V amplitudes and wave I-III, III-V, I-V intervals) between before and after the MRI examinations. Our findings may suggest the rarely temporary impact of MRI noise on ABR in neonates who underwent a 3.0T MRI.
