| Diagnostic Services - Hysterosalpinography (HSG) |
| The hysterosalpingogram is the primary screening test for abnormalities in female reproductive anatomy. Under x-ray imaging, liquid dye is injected into the uterus to characterize the shape of the uterine cavity. If the fallopian tubes are open, dye will be observed to be spilling out of the fallopian tubes. Once the dye spills from the tubes, the manner in which it spreads through the abdomen can provide some information regarding the presence or absence of adhesions or scarring around the tubes.
It is important to note that there are inherent false positives and negatives with HSG as a screening test. Tubes that appear blocked on HSG may actually be patent under direct vision with laparoscopy (up to a 40% rate of false alarm). Also, patent or open tubes with HSG do not always mean the tubes are healthy and fully functional (tubes can be chronically inflamed or surrounded by adhesions, yet still be patent). |
