What is a Ductogram (Galactogram)?

A (galactogram) is a procedure that uses mammography along with the injection of contrast material into the nipple to visualize the breast’s milk ducts. This non-invasive procedure is helpful when the patient has nipple discharge but has an otherwise normal mammogram. Ductograms are performed in the mammography room by an interventional radiologist and is an out-patient procedure. Ductograms are helpful in determining the cause of nipple discharge and diagnosing ductal ecstasia (swollen/clogged milk ducts), fibrocystic changes, interductal papillomas (wart-like, non-cancerous tumors that grow inside the duct) and breast cancer.
