Invenia™ Automated Breast Ultrasound (ABUS)

About 40 percent of women have dense breast tissue. For these women, mammograms alone may not be enough to find breast cancer.

Ultrasound, when combined with mammography, can increase the accuracy and detection of breast cancer in dense breasts by 35.7 percent; which is double the detection rate when only using mammography.

Invenia ABUS is the only FDA-approved system for breast cancer screening when used in combination with mammography in women who have dense breast tissue.


Unlike 2D or 3D mammography, which uses radiation, ABUS screening uses sound waves to create 3D pictures of the breast tissue. 

Appointment Information

The exam takes approximately 15 minutes and provides your doctor with clear 3D ultrasound images.

Radiologists can look through hundreds of breast tissue image “slices,” looking at layers of dense tissue to find breast cancers which may have been missed on a mammogram. This is different than routine ultrasound of the breasts, since the images from ABUS allow you to see in projections that routine ultrasound cannot. That results in the ability of physicians to detect more breast cancers and fewer false negatives (findings due to images which are not cancer). A mammography technologist will complete the ABUS exam, and a radiologist will read the results.
