As mentioned previously, although extra superior detailed sonograms (specialized examinations) are acceptable for patients with recognized threat components, all standard examinations should embrace a full anatomic survey. An overview of a number of the more common fetal malformations that might be acknowledged at the time of a standard ultrasound examination is introduced later on this chapter.

Since then, the know-how has progressed to the purpose that even comparatively inexpensive ultrasound machines yield detailed real-time photographs of the fetus.

A less complicated semiquantitative methodology is to diagnose polyhydramnios when the single deepest pool measures higher 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 often performed at about 20 weeks, or 5 months.
