Abstract
A system and method for ultrasound imaging of breast tissue by injecting an ultrasound contrast agent into a duct lumen of a patient's breast to enhance the imaging of one or more ducts within a specified lobe of the breast to improve characterization of a lesion or lesions within the duct system of the specified lobe are disclosed. The ultrasound contrast agent used to improve breast imaging may be injected into the duct lumen through an orifice on the nipple and/or a duct wall into the duct lumen. The ultrasound contrast agent may be injected prior to and/or during ultrasound imaging. The ultrasound contrast agent may be an acoustically detectable gas such as a halogenated hydrocarbon, halogenated alkane gases, nitrogen, helium, argon and/or xenon. The halogenated alkane gas may be a perfluorinated hydrocarbon such as saturated perfluorocarbon, unsaturated perfluorocarbon, and/or cyclic perfluorocarbon. The acoustically detectable gas may alternatively be mixed in a liquid solution.
