This is a non-randomized trial of 450 women with a breast abnormality, who are scheduled for a breast biopsy of this abnormality. The study will be conducted at two clinical sites. The primary objective of this trial is:

To evaluate if quantitative 3D Subharmonic imaging (SHI) or pulse inversion harmonic imaging (HI) can improve the characterization of benign and malignant breast masses (independently or in combination with other imaging modes) compared to x-ray mammography, fundamental grayscale ultrasound (US) or power Doppler imaging (PDI).

The secondary aim of this trial is:

To compare quantitative (bifurcations \& vessel length) and semi-quantitative (blood pool \& parametric imaging) measures of the vascular morphology of breast lesions determined by pathology and by SHI.

This is an open-label, non-randomized trial that will be conducted at two clinical sites (the Breast Imaging Centers at Thomas Jefferson University (TJU) Hospital and University of California, San Diego (UCSD) Hospital). All 450 subjects will receive at most two IV bolus injections of Definity (Lantheus Medical Imaging, Billerica, MA), will undergo an unenhanced (baseline) and Definity contrast-enhanced US imaging study for evaluation of a breast mass or breast abnormality without mass, and will be scheduled to undergo a clinically indicated biopsy of the breast lesion under investigation.

Quantitative Subharmonic Breast Imaging

Characterization of benign and malignant breast cancer lesions is compared by each imaging method which evaluates vascular activity. Imaging methods to be compared are 3D Subharmonic imaging (SHI) or pulse inversion harmonic imaging (HI), fundamental grayscale ultrasound (US) or power Doppler imaging (PDI). Data will be analyzed qualitatively.
