A breast ultrasound exam is primarily used to further evaluate breasts after a mammogram, breast MRI or clinical findings, often to help answer a specific problem or concern. A breast ultrasound can also be performed as a screening study of both breasts to supplement mammography in women with dense breasts.
The ultrasound uses sound waves to capture images of concern. Although a mammography is the best screening tool available to detect breast cancer, a breast ultrasound is an important tool that helps provide a more detailed understanding of a patient's breast health.
