Answer

Answer

A ductogram, or galactogram, is sometimes helpful for determining the cause of nipple discharge. In this specialized examination, a fine plastic tube is placed into the opening of the duct in the nipple. A small amount of contrast medium is injected, which outlines the shape of the duct on a mammogram, and shows whether a mass is present inside the duct.
