Ultrasound

Ultrasound involves the use of sound waves to pass inside a mother's body to create a picture of the fetus and uterus. Ultrasound does not involve any radiation exposure and is safe in pregnancy. Ultrasound can be used to determine the age, size, and anatomy of the fetus as well as look at the mother's uterus and cervix.

3D Ultrasound

Three-dimensional and four-dimensional ultrasounds
Three-dimensional (3D) and four-dimensional (4D) ultrasounds are both sophisticated technologies that produce a more life-like image of the infant. The difference between the two is that 3D images are still photographs, while 4D images show the baby moving.

Perinatologists in Bridgeport Hospital's Antenatal Testing Unit use these advanced images as an addition to standard ultrasound (2D) when the baby is being evaluated in the womb.

For example, 3D/4D ultrasounds give a better image of the baby’s features when a perinatologist is concerned about abnormalities of the lip, hands or feet. These more detailed images may also help you understand what the physician is seeing.
