What is the Breast Ultrasound Procedure, Purpose

A breast ultrasound is a diagnostic test that uses sound waves to create an image of the inside of the breast. 

It is used to evaluate masses or lumps that cannot be seen on a mammogram. 

Ultrasound is also used to help guide a needle biopsy of a suspicious area. 

The test is performed by a radiologist 

who will place a gel on the breast and then press a hand-held device called a transducer against the skin. 

The transducer emits sound waves that bounce off structures inside the breast and are converted into electrical signals. 

These signals are then displayed on a computer screen as images.
