Ultrasound and Fetal Monitoring

Ultrasound is an important and non-invasive way for your doctor to monitor the health of your pregnancy.

State-of-the-art ultrasound, timely results

Our doctors have expertise in the use of high-resolution ultrasound including:

  • The most accurate first trimester screening for abnormalities offered anywhere in the state
  • Advanced second trimester ultrasound diagnosis and fetal therapy
  • High-resolution ultrasound with 3-D and 4-D technology
  • Ability to make CDs of your ultrasound

Most patients can have ultrasound testing on the same day as a regular prenatal checkup.

Timing and purpose of your ultrasound test

You and your care provider will decide how often you will have ultrasound screening. Typically, patients have an ultrasound screening in their first trimester and another at 18-20 weeks to check the baby's growth, anatomy, position of the placenta, and amount of amniotic fluid around the baby (or babies). Care for higher-risk pregnancies may include a series of ultrasounds as we keep close watch over the health and development of your baby (or babies).

Fetal monitoring

Occasionally, if there is any concern for the health and development of your baby, you may visit fetal monitoring where we will monitor your baby's heartbeat and other vital signs. Learn more
