We assessed the phase distribution of the neonatal brain
using phase difference image. Phase difference image was
created with a combination of the magnitude and masked
phase image with relatively small positive phase using
3D gradient echo-planar imaging. Signal ratio at the
posterior limb of the internal capsule, the corpus
callosum, and the semiovale center was calculated. As a
result, a certain phase distribution was noted in
neonatal brain, which was different from that of
fractional anisotropy at diffusion tensor imaging.
