Ultrasound imaging of the breast uses sound waves to produce pictures of the internal structures of the breast. It is used to help diagnose breast lumps or other abnormalities found during a physical exam, or on a mammogram or breast MRI. Ultrasound is safe, noninvasive, and does not use radiation.
A breast ultrasound typically isn’t used as a screening mammogram, instead it can help diagnose breast lumps or other abnormalities.
