This is a normal fetal ultrasound performed at 17 weeks gestation.
The development of the brain and nervous system begins early in
fetal development. During an ultrasound, the technician usually
looks for the presence of brain ventricles. Ventricles are spaces
in the brain that are filled with fluid. In this early ultrasound,
the ventricles can be seen as light lines extending through the
skull, seen in the upper right side of the image.
