Enlarged ventricles, or ventriculomegaly can indicate several conditions (Figure 12). Abnormal NT at 11-14 weeks is an indication for genetic counseling, and early second trimester ultrasound at 14-16 weeks should be considered. 36 week ultrasound pictures will give you a good sneak peek at the little face youll meet in a few weeks! . Ventriculomegaly is also present in the Dandy-Walker malformation (Figure 13), a malformation characterized by absence of the middle portion of the cerebellum, known as the vermis, with cystic dilation of the fourth ventricle visible in the posterior fossa. Late in the first trimester, the brain can be imaged in the transverse plane, identifying both hemispheres and midline structures. haha Its incredible to see how tiny we all start out and then grow into masters of the earth.

Imaging findings were not mutually exclusive (i.e., a neonate may have had more than one finding). Although the heart structures aren't yet fully developed at six weeks gestation, it's possible to see the electrical impulses of their developing heart (sometimes referred to as embryonic cardiac activity). In the same image used to assess NT, the profile can be evaluated. Here you have the most useful information about your 36 week Pregnancy.
