What does the medical abbreviation HSG mean?

The medical abbreviation HSG stands for hysterosalpingography. It is an X-ray procedure used to examine the uterus and fallopian tubes. Performed by an obstetrician or radiologist, an HSG involves the injection of a contrast agent into the cervix which creates images of the uterus and fallopian tubes to see if they are open. This test can be used to diagnose conditions such as scar tissue, adhesions, polyps, and tumors.
