Obstetrical Ultrasound

Obstetrical ultrasounds are ordered to follow the growth and health of your fetus (unborn baby).  

Ultrasound is a safe, non-invasive and painless procedure for you and your baby.

This procedure is used to establish the presence of the baby in the uterus, estimate the age of the baby, identify abnormalities, the position of the baby, and the amount of amniotic fluid around the baby.
