What is a Galactogram?

A galactogram (also called a ductogram) is a test that examines your milk ducts in your breast. With the use of a special x-ray contrast and mammograms, a radiologist can determine if there are any abnormalities in your ducts.

Who benefits from a Galactogram?

A particular test is recommended for patients with suspected milk duct abnormalities. The most common symptom for a nipple abnormality is nipple discharge. Speak to your doctor if you are having any sudden changes with your nipple, such as nipple discharge.

How is the Exam Performed?

A trained radiologist will evaluate your nipple for any discharge. Once the duct that is producing the discharge is identified, the radiologist will slide a very tiny catheter through the desired duct. The contrast agent is then injected into this duct with the use of a syringe attached to the catheter. Special mammograms will be taken after the contrast has been injected. The radiologist will study the ductal pathway and determine if any filling defects or 'road-blocks' are seen.

How to Prepare

There is no specific type of preparation for this test but it is recommended that you eat beforehand as it could become a lengthy process to find the exact duct that is producing the discharge. Also, it is very important to not try to express nipple discharge yourself before this test. This will ensure that the doctor will be able to better express the discharge on the day of your exam. If no discharge is present on the day of the exam, it is possible that the exam may have to be rescheduled.

Getting Your Results

You will receive your results from your doctor. Sometimes the preliminary results will actually be given to you on the same day as this exam from the performing radiologist. If a filling defect is identified, you may be recommended to a surgeon for the removal of this area.
