MRI acoustic exposure has the potential to elicit
physiological distress and impact development in preterm
and term infants. To mitigate the risk, a novel acoustic
quiet body coil for a neonatal MR system has been
developed to reduce the sound pressure level experienced
by neonates during MR procedures. Acoustic
characterization demonstrated the quiet coil was
consistently quieter, on average of 9 dBA, compared to a
conventional body coil. The quiet coil provides a robust
way of attenuating noise that does not require imaging
pulse sequence modifications, is patient-independent,
and synergistic with other attenuating practices.
