3-D breast ultrasound
somo-v Automated Breast Ultrasound system (ABUS)
More than 40 percent of women have dense breast tissue, which makes tumors harder to see with mammography alone. To improve detection, Community Hospital offers a 3-D breast ultrasound in conjunction with routine screening mammography.
In a clinical study in which Community Hospital took part, detection increased 30 percent when mammography was combined with ultrasound using the somo-v® Automated Breast Ultrasound system (ABUS).
Should you have a 3-D ultrasound? Your mammography provider can tell you whether you have dense breast tissue and could potentially benefit from additional screening. Beginning in April 2013, providers in California will be required to notify women when their mammograms show that they have dense breast tissue.
What to expect
Before starting the exam, the ABUS operator attaches a sheer membrane to the ultrasound scanner. A layer of coupling lotion is applied to the breast to ensure good contact between the ultrasound scanning device, called a transducer, and the skin to capture a 3-D picture of the breast tissue between the skin and the chest wall. To ensure the best image quality, the stabilizing membrane of the somo•v ABUS is firmly positioned on the breast during scanning, which gently flattens the breast tissue against the body and prevents breast movement.
First, a 10-second preview scan automatically determines the patient's unique breast tissue signature so the ideal ultrasound imaging parameters can be set by the software. Then, the actual scanning begins and lasts about 60 seconds. The technologist follows the scanning on a display monitor in real-time to ensure proper breast coverage and tissue contact. When the scan is complete, the technologist reviews the image on the monitor and uses the touch-screen to confirm the nipple location, breast and view type. Typically, three scans are performed on each breast for a complete scan of the breast volume.
The ultrasound images are then sent to the somo•VIEWer workstation, where a radiologist can review them in a variety of 3-D layouts.
