This is a detailed evaluation of your baby’s development at a time when most structural abnormalities can be identified. Special attention is given to the brain, spine, heart, kidneys, bladder, stomach, bowel, abdominal wall, face and limbs. The location and development of the placenta and umbilical cord, amniotic fluid volume, and cervical length are also assessed. Measurements of the head, abdomen, femur and humerus will be obtained and used to determine the baby’s size and rate of growth.
