Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This pilot clinical trial studies how well contrast-enhanced subharmonic ultrasound imaging works in improving the characterization of adnexal masses in patients undergoing surgery. Contrast-enhanced subharmonic ultrasound imaging uses high-frequency sound waves to produce images of internal organs and when combined with an ultrasound agent such as perflutren lipid microspheres, may help improve imaging and management of adnexal masses.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

PRIMARY OBJECTIVES:

I. To develop qualitative subharmonic imaging (SHI) or SHI-derived quantitative biomarkers.

II. To generate pilot data for a study to evaluate if they improve the characterization of benign and malignant adnexal masses compared to standard ultrasound or contrast enhanced magnetic resonance imaging (MRI) or the risk of malignancy index (RMI).

SECONDARY OBJECTIVES:

I. To compare the SHI depiction of adnexal masses' neovascularity in humans to intra-tumoral microvascular density (iMVD) obtained from CD31 an immunohistochemical marker of angiogenesis.
