Currently, the question of when the ossification center
of atlanto-axial vertebrae appears and could be detected
by MR in human fetuses hasnt been fully answered yet.
In order to address this question, we used the
three-dimensional T2-weighted MR imaging technique to
investigate the development process of ossification
center in postmortem fetuses. By using a
high-spatial-resolution T2-SPACE MR protocol, the
changes of the ossification center of atlas and axis
during fetus developing could be observed clearly. The
emerging time of the ossification center of the axis
dens could be a good sign for determining the fetal age.
