Galactography is a particular X-ray of the breast to study the lactiferous ducts, which are the structures devoted to the production of breast milk.
Lactiferous ducts are not able to absorb X-rays unless they are filled with a substance called contrast medium. To allow the injection of the contrast medium inside the ducts, in the case of a milk duct orifices smaller than the needle’s cannula, it is necessary to dilate the orifice with the dilators we provide.
