Fluoroscopy: Hysterosalpingogram A hysterosalpingogram is a study of the female reproductive system to specifically determine if the fallopian tubes are open between the ovary and the uterus. Hyserosalpingograms are performed to determine the possible causes of infertility and to check the efficiency of intrauterine devices. To visualize the uterus and fallopian tubes, a small amount of contrast material is injected into the uterus, which fills it up and travels along the fallopian tubes. It appears dark on the x-ray image, outlining the reproductive structures. A hysterosalpingogram is performed in a specialized x-ray room with the radiologic technologist, the OB/GYN physician, and a radiologist. Before the procedure begins, the patient will change into a hospital gown. The majority of the procedure will be similar to a pap smear, which is performed by the OB/GYN physician until the contrast is ready to be injected. At that point, an advanced x-ray machine called a fluoroscope will be positioned over the patient by the radiologist to capture images of the contrast material as it is injected into the uterus and fallopian tubes. The fluoroscope is capable of capturing images during movement, much like a home video camera, which are displayed on a television monitor in the room. During the injection, cramping may occur. This part of the procedure will take only a few minutes. Once all the necessary images are taken, the exam is finished. You will be given a sanitary pad to capture the leakage of the contrast. Some spotting may occur, which will diminish within 24 hours. The OB/GYN physician will be able to share with you the findings of your study immediately. If you have any questions about your exam after you have returned home, contact your OB/GYN physician.
