Galactogram / Ductogram
What is a Galactogram, or Ductogram?
A galactogram, also called a ductogram, is a test done if you are having persistent nipple discharge from a single duct, and your mammogram is normal.
A tiny tube is inserted into the duct and a tiny amount of iodine contrast dye is injected into the duct. Several mammogram pictures are then obtained, with the ducts outlined by the iodine contrast dye. This shows whether there is anything inside the duct which could be producing the discharge. Most women report that this 30 minute test is not painful. When the duct is filled with fluid, it may feel a cramping sensation similar to what many women experience with their menstrual cycle.
