Galactography or ductography (or galactogram, ductogram) is a medical diagnostic procedure for viewing the milk ducts. The procedure involves the radiography of the ducts after injection of a radiopaque substance into the duct system. The procedure is used for investigating the pathology of nipple discharge.
|Purpose||diagnostic procedure for viewing the milk ducts.|
Galactography is capable of detecting smaller abnormalities than mammograms, MRI or ultrasound tests. With galactography, a larger part of the ductal system can be visualized than with the endoscopic investigation of a duct (called galactoscopy or ductoscopy).
The standard treatment of galactographically suspicious breast lesions is to perform a surgical intervention on the concerned duct or ducts: if the discharge clearly stems from a single duct, then the excision of the duct (microdochectomy) is indicated; if the discharge comes from several ducts or if no specific duct could be determined, then a subareolar resection of the ducts (Hadfield's procedure) is performed instead.
