Galactogram

This test may be used to investigate when there is spontaneous, one-sided nipple discharge, especially when it is bloody or blood stained. There must be active nipple discharge before this can be done.

A radiologist threads a special blunt catheter into the milk duct, injects dye into it and then takes some mammographic pictures. The dye produces a visual “map” for tracing the source of the discharge and will help the doctor diagnose the problem.
