  • Ultrasound During Preganancy
  • A prenatal ultrasound uses sound waves and a computer screen to show a picture of your baby inside the womb.
  • Ultrasounds can help your health care provider see how your baby is growing and developing.
  • Your provider also may use ultrasounds to see if other tests need to be done to check on your baby’s health.
  • There are several types of ultrasounds and they are safe for you and your baby when done by a trained health care provider.
  • To confirm (make sure) you’re pregnant
  • To check your baby’s age and growth. This helps your provider figure out your due date.
  • To check your baby’s heartbeat, muscle tone, movement and overall development
  • To check if your baby is in the heads-first position before birth
  • To examine your ovaries and uterus (womb). Ovaries are where eggs are stored in your body.
  • Your provider also uses ultrasound for screening and other testing. Screening means seeing if your baby is more likely than others to have a health condition; it doesn’t mean finding out for sure if your baby has the condition.

  • To screen for birth defects, like spina bifida or heart defects. After an ultrasound, your provider may want to do more tests, called diagnostic tests, to see for sure if your baby has a birth defect. Birth defects are health conditions that a baby has at birth. Birth defects change the shape or function of one or more parts of the body. They can cause problems in overall health, in how the body develops, or in how the body works.
  • To help with other prenatal tests, like chorionic villus sampling (also called CVS) or amniocentesis (also called amnio). CVS is when cells from the placenta are taken for testing. The placenta is tissue that provides nutrients for your baby. Amnio is a test where amniotic fluid and cells are taken from the sac around your baby.
  • To check for pregnancy complications, including ectopic pregnancy, molar pregnancy and miscarriage.
