A Hysterosalpingography is simply an x-ray that is used to inspect the uterus (womb) of a woman as well as fallopian tubes (which transmit the eggs from the ovaries to the uterus). It consists of contrast material so fallopian tubes and uterus show up well on the images. It is known as fluoroscopy which is used to create a video image instead of a still image.
A radiologist keeps track of the dye while moving it along the reproductive organ. Then, they can look for any blockage in the fallopian tubes or any abnormalities in the uterus.
