A ductogram (duct-o-gram) provides an image of the inside of a breast. It is sometimes used to find the cause of nipple discharge. A ductogram is also called a galactogram.
In this test, a small amount of dye is put into one of the ducts in the nipple through a tiny plastic tube. The dye can be seen on an x-ray, which can then show if there’s a tumor inside the duct.
