Using high-frequency sound waves instead of radiation, breast ultrasound forms an image of internal breast structures as the sound waves pass through then bounce back from various tissues.
Breast ultrasound is most often used to image a specific area of the breast where a lump or other abnormality is suspected. Unlike x-rays, ultrasound can discern between a solid mass and a cyst that’s filled with fluid, for example. Tiny lesions that are impossible to detect by hand also are often first seen via an ultrasound. In short, ultrasound is used for very specific imaging needed within the breast where other imaging techniques aren’t as well suited.
Preparing for your ultrasound
There are no special procedures you need to undergo before your breast ultrasound.
