A hysterosalpingogram, also called a uterosalpingogram, is a diagnostic procedure which is used to investigate a woman’s fertility issues. During this procedure x-ray is combined with contrast fluoroscopy to examine the uterus and fallopian tubes.
During the procedure, the woman’s fallopian tubes and uterus are filled with a high-contrast dye via catheter insertion. Next, the woman undergoes an x-ray. The addition of the dye allows the radiologist to take x-rays that are more detailed and better show the anatomy of the uterus and fallopian tubes. By examining the x-rays, the radiologist can look at the shape and structure of the organs, look at whether the fallopian tubes are blocked, and whether any scarring exists which might prevent pregnancy.
In addition to examining the structure of the fallopian tubes and uterus, the radiologist can also look at whether any abnormal growths are present in the organs. These might include tumors, uterine fibroids, or adhesions, any of which might prevent pregnancy and in the case of malignant tumors may pose a significant risk to the woman’s health.
A third use of the procedure is to examine the fallopian tubes after surgery such as tubal ligation or to remove a fallopian tube blockage.
