A galactogram or ductogram is a procedure that is sometimes helpful in determining the cause of nipple discharge.

  • Cream is placed on the nipple for local anesthesia, along with warm compresses to help stimulate a nipple discharge.
  • The radiologist inserts a small catheter into the nipple through which X-ray dye will be injected.
  • The technologist then takes several low dose mammograms of the breast, after which the catheter is removed.
