Second trimester anatomic survey

Second Trimester

The anatomic survey (or anomaly scan) 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, sex, 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.

An additional second-trimester scan may also be ordered to answer a specific clinical concern, such as preterm labor, low-lying placenta, and bleeding, to name a few.

A fetal echocardiogram is a detailed examination of the fetal heart that is often performed in the second trimester.
