Brief Summary:
The purpose of this study is to determine if breast imaging with ultrasound can be improved by using 1) a ultrasound attachment with two transducers and 2) a contrast agent. These changes might allow smaller blood vessels to be seen than under the way breast ultrasound is usually performed.

Condition or disease Intervention/treatment Phase
Breast Cancer Breast Abnormalities Procedure: Ultrasound Imaging with Contrast Not Applicable

Detailed Description:

The purpose of this study is to determine if performing ultrasound with an attachment made up of two transducers (rather than just a single transducer) will provide more information about the blood vessels in the breast than the current attachment.

The study will also examine the question of whether use of an ultrasound contrast agent will the scanner to see smaller blood vessels than are detected without the agent.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 0 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: Characterization of Breast Masses Using a New Method of Ultrasound Contrast Agent Imaging in 3D Mapping of Vascular Anomalies
Study Start Date : April 2001
Actual Primary Completion Date : August 2010
Actual Study Completion Date : December 2010

Arm Intervention/treatment
Experimental: Ultrasound Imaging
Ultrasound Imaging with Contrast
Procedure: Ultrasound Imaging with Contrast

An ultrasound contrast agent, Definity, will be administered started through the IV line already in use. The imaging will be performed to map vascular flow.

The breast will be scanned by a double ultrasound transducer system in a holder over the area of the breast to be biopsied. The machine will be set with different settings and the scan repeated, possibly multiple times.
