What’s the difference between a Hysterosalpingogram (HSG) and a Sono-Hysterogram?
Posted on September 30, 2010
This just happens to be one of my most frequently asked questions, and it's a good one. Both are can be very important tests. Some women need only one, some both. In this blog you will see pictures and explanations. I enjoyed putting this blog together because I like taking things that are a little complicated and breaking them down into simple pieces to help make the readers understand every day things that were never made clear to them. Despite this I realize that there are some of you that get very intimidated when shown pictures of anything medically related, so I am sorry if some of this compounds your frustration. Give this one a shot and see how it goes.
Hysterosalpingogram, also known as the hysterogram or HSG. Hystero means uterus, salpingo means tube, so it's a test to evaluate both the uterus and tubes. It's a dye test that uses an x ray. As far as the patient is concerned, it starts with a speculum, like a pap smear. The doctor, through various techniques mentioned in previous blogs, squirts some dye into the uterus and it then runs out the tubes. The dye is actually as clear as water, but it's called dye because it is white on an x ray. The dye then shows the shape of the interior of the uterus and the tubes.
Let's start with the uterus. This is picture of a HSG x ray.
