Synopsis

Keywords: Neonatal, Neonatal

Motivation: Neonatal brain MRI is the preferred modality for detecting neonatal brain injury resulting in significant neurodevelopmental disorders.

Goal(s): The objective of this work is to design a 32-channel semiflexible receive coil dedicated for brain MRI in neonates within 12 months at 3T.

Approach: Imaging studies in phantom and human subjects have been performed on a clinical 3T MRI system to validate the design.

Results: Compared with the commercial adult head coils, the proposed coil showed performance improvement in SNR. The high-quality brain images were acquired in clinical examinations using the proposed coil, which indicated the potentiality for the application in neonatal clinical diagnosis.

Impact: A 32-channel semiflexible receive coil array dedicated for brain MRI in neonates within 12 months at 3T was developed. The acquired high SNR and high-spatial resolution MR images indicated the potentiality for the application in neonatal clinical diagnosis.
