A 5D ultrasound is an imaging test that uses sound waves to create pictures of your baby in the womb. The test is also called a fetal echocardiogram or cardiac ultrasonography.
During a 5D ultrasound, the technician will use a special probe to send sound waves through your abdomen. The waves will bounce off your baby's heart and create an image on a monitor.
The 5D ultrasound can provide more detailed images of your baby's heart than a standard 2D ultrasound. It can also help doctors diagnose certain heart conditions, such as defects in the valves or chambers of the heart.
If you're pregnant and have been told that your baby has a heart condition, you may be scheduled for a 5D ultrasound. This test is usually done in addition to other tests, such as a fetal echocardiogram or genetic testing.
