Each nipple has approximately six to ten ducts from which breast milk flows during breast feeding. The ductogram is a procedure that may be performed if you note a discharge from the nipple. It involves the insertion of a tiny, blunt needle into the affected duct identified by the radiologist. Contrast solution is then injected into the duct. Mammogram films are taken to determine if the duct is blocked or dilated.
You may feel little to no pain when the needle is inserted, although you may feel pressure or temporary discomfort when the contrast solution is injected.
A ductogram can only be performed if there is discharge that can be expressed by the radiologist at the time of your scheduled procedure.
