Breast Ultrasound

An ultrasound exam may be used to evaluate lesions seen on the mammogram to find out whether they are solid or filled with fluid (a cyst). This imaging technique is also used to evaluate lumps that can be felt but are difficult to see on a mammogram.

During the exam, the sonographer spreads a thin coating of lubricating jelly over the area to be imaged to improve conduction of the sound waves. A hand-held device, called a transducer, is placed on the breast and directs the sound waves through the breast. When the sound waves are reflected back from the tissues within the breast, the patterns form a two-dimensional image of the breast on a screen.

Although breast ultrasound is a valuable problem solving tool, it is not a substitute for mammography. There are some signs of early breast cancer that can be seen only on a mammogram. Only mammographic screening has been proven to save lives from breast cancer.

Breast Imaging Center of Excellence

St. Joseph Hospital is designated a Breast Imaging Center of Excellence by the ACR. This designation assures that St. Joseph Hospital meets standards for radiation safety and image quality. By awarding facilities the status of a Breast Imaging Center of Excellence, the ACR recognizes breast imaging centers that have earned accreditation in mammography, stereotactic breast biopsy, and breast ultrasound (including ultrasound-guided breast biopsy).
