This week we have a few random 3d reconstructed images .

first is a great vessel crossing ; ideally the fetus should be on its back facing the examiner .and should be still for the duration of the 3 D sweep.This view , if normal  essentially rules out transposition of great vessels.

the next is a 3 d reconstruction of fetal pulmonary vasculature.

viewing atleast one o r two pulmonary veins draining into the left atrium effectively rules out  total anomalous pulmonary venous drainage

all 4 pulm veins are seen in this reconstruction

the next is a reconstruction of pericallosal artery

.viewing the peri callosal artery in full implies that the corpus callosum is formed normally.

the next is a reconstruction image of aortic arch
