This clinical trial studies the use of contrast-enhanced ultrasound (CEUS) in estimating tissue pressure in patients with breast cancer. Diagnostic procedures, such as CEUS, may help estimate tissue pressure noninvasively.



I. To determine if the 3-dimensional (3D) subharmonic aided pressure estimation (SHAPE) results can be used to estimate interstitial fluid pressures (IFPs) in breast tumor and its surrounding tissue.


I. To determine if the malignancy of breast tumor can be predicted by the 3D SHAPE results.


Patients undergo ultrasound without contrast. Patients then receive perflutren lipid microspheres (Definity) intravenously (IV) over 15 minutes and undergo CEUS.
