Ultrasound sonography is the process in which high-frequency sound waves scan the mother's womb to produce an image of the unborn baby, whose size and shape can then be assessed. The first-trimester screen is a different procedure that involves blood tests and ultrasound to assess a woman's risk of having a baby with certain chromosomal conditions. Amniocentesis and chorionic villus sampling (CVS) are invasive tests that involve taking a sample of amniotic fluid or placental tissue, respectively, and are typically done to diagnose certain genetic conditions.
