Galactography.

Galactography is a quick effective means of evaluating nipple discharge. It is especially indicated when the effluent is bloody. A description of the procedure is discussed. The radiographic findings in both normal and abnormal studies are presented. Abnormal findings include filling defects, duct cut-off, duct encasement, extravasation, and duct ectasia. The radiographic diagnosis corresponded with pathologic findings in 12 of 16 cases (75%), although in two cases no radiographic or pathologic abnormality was found to explain the bloody discharge.
