“Our physicians understand the combination of excitement and anxiety that comes with pregnancy. We make it a priority to provide with clarity and sensitivity the information that every pregnant woman needs in a way that they can understand, while being careful to avoid alarming them unnecessarily.”

- Dr. Stephen Todd Chasen, Director of Obstetric Imaging

Perhaps no other technology in recent times has been as effective in successfully monitoring pregnancies as Ultrasonography. The faculty of the Ultrasound Services Unit in the Department of Obstetrics and Gynecology at Weill Cornell Medicine has been leaders in fetal evaluation and prenatal diagnosis since the unit's inception in 1989; using the most advanced ultrasound machines—some with 3D capabilities.

All members of the unit have been at the forefront in advocating that all pregnant women have access to quality ultrasound during pregnancy. The unit's sonographers and Maternal-Fetal Medicine physicians are highly skilled in evaluating fetal development, and identifying a wide variety of abnormalities. They perform detailed evaluation of fetal anatomy in the second trimester, and can identify or exclude many types of birth defects. First-trimester ultrasound, commonly performed to evaluate the risk of genetic abnormalities, has allowed for the early detection of some major abnormalities before the second trimester. 

If physicians suspect or diagnose fetal or maternal complications, they will work with you and your obstetrician to provide you with access to and coordinate care with some of the world’s finest specialists. Together, we will develop the very best treatment options for you and your baby. Detecting early evidence of complications and establishing an effective course of action helps everyone achieve the goal of healthy mothers delivering healthy babies.

All women having their ultrasound completed at the Ultrasound Services Unit will have the opportunity to consult with one of the Weill Cornell Maternal-Fetal Medicine specialists to discuss any ultrasound findings. If complications are suspected, our physicians will work with patients and their obstetricians in formulating the best plan.
