Vibro-Acoustography Imaging in Diagnosing Breast Masses in Women With a Breast Mass or Breast Cancer
Identification and Differentiation of Breast Masses by Vibro-Acoustography
RATIONALE: New diagnostic procedures, such as vibro-acoustography imaging, may be an effective method of diagnosing breast cancer.
PURPOSE: This clinical trial is studying how well vibro-acoustography imaging works in diagnosing breast masses in women with a breast mass or breast cancer.
研究概览
详细说明
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.
