Breast ultrasound is an imaging test that uses sound waves to look at the inside of your breasts, it can help to find breast problems. It also lets your healthcare provider see how well blood is flowing to areas in your breasts. This test is often used when a change has been seen on a mammogram or when a change is felt, but does not show up on a mammogram.
Ultrasound is safe to have during pregnancy because it does not use radiation. It is also safe for people who are allergic to contrast dye because it does not use dye.
