Brief Summary:

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.

Condition or disease Intervention/treatment
Breast Cancer Other: breast imaging study

Detailed Description:


  • 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.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 147 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: Identification and Differentiation of Breast Masses by Vibro-Acoustography

Arm Intervention/treatment
Experimental: breast imaging study Other: breast imaging study

1. A set of vibro-acoustography (VA) scans will be taken of the breast by an experimental vibro-acoustography device that uses ultrasound for imaging.

2- An ultrasound scan (sonography) of the breast using a clinical ultrasound machine may be taken during the procedure.

Primary Outcome Measures :
  1. Detection and differentiation of breast masses with an estimated specificity of ≥ 70% using vibro-acoustography (VA) imaging [ Time Frame: 25 minutes for Breast VA imaging ]
