About this study

The purpose of this study is to determine whether contrast-enhanced ultrasound (CEUS) can be used in diagnostic evaluation of breast lesions that cannot be seen using contrast-enhanced MRI (CEMR) and contrast- enhanced dual energy mammography (CEDM).   If so, patients can undergo US guided biopsy which is more comfortable for patients and more cost effective.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.
