Mammography with tomosynthesis has incorporated this new technique, Contrast Mammography. It consists of injecting the patient with an iodinated contrast agent (the same one used in scans) prior to performing the mammogram. This contrast is captured by breast tumors and is represented in the image as a lit bulb in a dark room.
It allows for an increase in the sensitivity and specificity of the scan, helping to detect hidden lesions by providing functional information.
In certain cases, it is an alternative or complement to an MRI of the Breast.
