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.
Interventions
3 ml of Perflutren Lipid Microspheres (Definity) mixed in 50 ml of saline is infused at a rate of approximately 4ml/min
