As mentioned previously, although more advanced detailed sonograms (specialized examinations) are acceptable for patients with identified danger components, all commonplace examinations ought to include a full anatomic survey. An overview of a few of the more widespread fetal malformations that can be recognized on the time of a normal ultrasound examination is presented later on this chapter.

A easier semiquantitative methodology is to diagnose polyhydramnios when the one deepest pool measures larger than 8 cm ( Fig. 9-22 ) and oligohydramnios when the shallowest pool measures lower than 2 cm in two dimensions .

The full anatomy ultrasound is typically performed at about 20 weeks, or 5 months.
