Ductograms are performed on patients with active nipple discharge. The breast will be manipulated to produce the discharge in the examination room, thereby identifying the specific duct. A needle is then inserted into the duct and contrast material is injected. Mammography images are then taken as the contrast material will highlight the specific duct and assist the radiologist in identifying abnormalities.

There is no preparation for this exam, however, there needs to be active discharge.
