Vibro-Acoustography Imaging in Diagnosing Breast Masses in Women With a Breast Mass or Breast Cancer

OBJECTIVES: * To study in vivo detection of breast masses by vibro-acoustography (VA) imaging. * To evaluate the performance of VA imaging in differentiating between benign and malignant breast masses identified as BI-RADS 4 or 5. OUTLINE: Patients undergo clinical mammography of the breast, followed by vibro-acoustography (VA) imaging using ultrasonography over 90 minutes. Patients may also undergo further imaging using clinical ultrasonography.
