Diagnostic Study of Early Breast Cancer Using Ultrasound

Women who have imaging findings suggestive of DCIS, who are having breast ultrasound and who are candidates for surgery will be eligible. They will receive a contrast-enhanced breast ultrasound after the intravenous injection of a microbubble contrast agent which will show the microvascularity. A subset of women will also have ultrasound elastography performed of the abnormality to evaluate its stiffness.
