Breast Ductography (Intra-ductal Contrast X-Ray) — Deprecated
A breast duct X-ray uses contrast placed in a nipple duct to outline the duct system. This older, deprecated test is used mainly in selected cases.
["This older imaging test can show duct blockage or leakage but is now rarely performed."]

What is this test?
Breast ductography, also called a ductogram or galactogram, is an X-ray examination of the milk ducts in the breast. Contrast material is placed through the nipple to make the duct network visible on images.
Why might I need this test?
Historically, this test was used to evaluate abnormal nipple discharge, a possible blocked duct, or the location of a breast lump. Because it is deprecated, it is now performed only when a clinician determines that the information would be useful and other imaging is not more appropriate.
How is the test performed?
A clinician identifies a suitable opening in the nipple and gently introduces a small amount of contrast. X-ray images are then taken to show how contrast moves through the ducts, after which the contrast is removed.
How do I prepare for the test?
Follow the imaging center's instructions, as specific preparation may vary. Tell the care team about any prior contrast reaction, iodine allergy, pregnancy possibility, breast surgery, current infection, or recent breast biopsy before the procedure.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Abnormal duct filling may indicate a blocked or damaged duct, leakage, or an area that does not fill normally. Such findings may help explain nipple discharge or guide further evaluation, but they do not diagnose cancer by themselves. Results should be interpreted with the breast examination and other imaging findings.
