The first step in the evaluation of the anatomy of the head and brain is to perform biometry, which includes the biparietal diameter and head circumference. The fetal head or brain at 12–13 6/7 weeks can be imaged in the three “classical” planes, namely axial, sagittal, and coronal. WebThere is no evidence that mechanical compression of the fetal head by uterine contractions causes cerebral ischemia, neurologic injury, or perinatal stroke.[8] Variable …
