Brief Summary
This is a diagnostic accuracy study to evaluate if two novel ultrasound (US) techniques, quantitative 3D subharmonic imaging (SHI) and Subharmonic Aided Pressure Estimation (SHAPE), used with an intravenous ultrasound contrast agent (Definity, Lantheus Medical Imaging, Billerica, MA), can track changes in locally advanced breast cancer (LABC) angiogenesis and interstitial fluid pressure (IFP), respectively, by studying women undergoing neoadjuvant chemotherapy before as well as with around 10% and 60% (in part 1) or 30% (in part 2) of the neoadjuvant chemotherapy treatment delivered and after completion of the neoadjuvant chemotherapy treatment. Results will be compared to MRI and pathology.

Outcome Measures
Primary Outcomes (2)
Subharmonic Aided Pressure Estimation (SHAPE) After Treatment for Complete Responders
To evaluate the ability of SHAPE, used with Definity, to track changes in interstitial fluid pressure (IFP) by studying women undergoing neoadjuvant chemotherapy before as well as with around 10% and 30% of the neoadjuvant chemotherapy treatment delivered and comparing results to MRI and pathology.
from baseline to completion of neoadjuvant chemotherapy, average of 6 months
Subharmonic Aided Pressure Estimation (SHAPE) After Treatment for Partial Responders
To evaluate the ability of SHAPE, used with Definity, to track changes in interstititial fluid (IFP) by studying women undergoing neoadjuvant chemotherapy before as well as with around 10% 30% of the neoadjuvant chemotherapy treatment delivered and after completion of the neoadjuvant chemotherapy treatment and comparing results to MRI and pathology.
from baseline to completion of neoadjuvant chemotherapy
Secondary Outcomes (2)
Subharmonic Imaging (SHI) Depiction of Breast Cancer Angiogenesis for Complete Responders
From baseline to after surgery
SHI Depiction of Breast Cancer Angiogenesis for Partial Responders
After surgery; on average 6 months
Study Arms (1)
Definity infusion
EXPERIMENTALInfusion of Definity (Perflutren Lipid Microspheres)
Interventions
3 ml of Perflutren Lipid Microspheres (Definity) mixed in 50 ml of saline is infused at a rate of approximately 4ml/min
