A hysterosalpingogram is an X-ray test that looks at the inside of the uterus and fallopian tubes, and the area around them. The test is used for several reasons.
A hysterosalpingogram involves the injection of radiographic dye into your uterus, and it must be performed by a radiologist or someone trained in radiographic imaging. The uterus fills with this dye, and if your fallopian tubes are clear, it will spill into your abdominal cavity. Pictures are taken using a steady beam of X-ray (fluoroscopy) as the dye passes through the uterus into the fallopian tubes.
SSG is done with help of ultrasonography and normal saline is instilled in to the uterine cavity. The patient is awake and can often watch the monitor with the physician to see the results of the study.
