Anatomical imaging of the neonatal brain is typically acquired using T2-weighted imaging based on either 3D fast spin echo (FSE) or 2D single shot FSE (SSFSE). While 3D imaging provides higher signal-to-noise ratio (SNR) and spatial resolution than 2D, its scan time is relatively long.In this study, we developed rapid 3D anatomical imaging for the neonatal brain using 3D steady-state free precession (SSFP) with T2 preparation. Our proposed method demonstrated similar T2 contrast to that of 3D FSE and 2D SSFSE while achieving shorter scan time than 3D FSE and higher through-plane resolution and higher SNR than 2D SSFSE.
