Other types of mammography
Seventy percent of important abnormalities detected by mammographic screening are impalpable and may require X ray guided stereotactic localisation. This may be followed by fine needle biopsy or open biopsy. In the latter case, the removed breast tissue may then be X-rayed to prove that the lesion has been excised.
Mammography can also be used to define the outline of ducts by injecting contrast - ductography.
