Why Yale Medicine?
  • We have vast experience and advanced ultrasound equipment and technology.
  • Highly skilled experts perform 16,000-plus ultrasounds annually
  • Pioneers in transvaginal ultrasound and for diagnosing various conditions

Since the mid-20th century, ultrasound has been used extensively to create a "picture" of what's happening inside our bodies. For pregnant women, it is an indispensable aspect to care. 

At Yale Medicine Maternal-Fetal Medicine, our physicians and sonographers perform more than 16,000 ultrasounds a year. 

"Experience counts. This is the only way we can approach the fetus like a patient. With sophisticated ultrasound, we now have ways to identify fetal problems and guide treatment," says Joshua Copel, MD, a Yale Medicine expert in prenatal diagnosis and fetal therapy and a professor of obstetrics, gynecology and reproductive sciences at Yale School of Medicine. "If a baby has an abnormal amount of fluid in the chest, we can use an ultrasound-guided needle to drain it out. Or we can deliver blood to the umbilical cord. The first of these types of transfusions were done here at Yale in 1984."

Think of ultrasound—sometimes called a sonogram—as sonar for the body. A small instrument called a “transducer” transmits high-frequency sound waves, bouncing them off structures in the body and using the reflected sound waves to paint a picture.

The sound waves can determine the distance, size, shape and consistency of an object. A computer compiles these results to create an image of the object, be it a fetus, an adult heart, or a tumor in the kidney.

Clinical Trials

New treatments for many conditions are tested in clinical trials, which ultimately bring lifesaving new drugs and devices to the patients who need them most. By participating in a clinical trial, you may get access to the most advanced treatments for your condition, and help determine their benefits for future patients.
