Abstract

Objective To investigate the feasibility and advantages of knee phased-array coil in neonatal brain MR imaging. Methods Conventional brain MR imaging was conducted on sixteen newborns on a 1.5 T MRI scanner. Imaging techniques, including T1- weighted imaging, T2-weighted imaging, T2 FLAIR imaging, and diffusion weighted imaging at the axial orientation, and T1-weighted imaging at the sagittal orientation, were respectively performed using a knee phase-array coil. The image quality was quantitatively evaluated with compared to that obtained from a traditional 8-channel head coil. Results The study was successfully conducted with all images free of artifacts. The signal-to-noise ratio of the images acquired with the knee phased-array coil was better than that with the head coil. Conclusion The knee phased-array coil is superior for neonatal brain imaging to the traditional head coil.
