Hysterosalpingography, also called uterosalpingography, is an x-ray examination of a woman’s uterus and fallopian tubes that uses a special form of x-ray called fluoroscopy and a contrast material.
An x-ray (radiograph) is a noninvasive medical test that helps physicians diagnose and treat medical conditions. Imaging with x-rays involves exposing a part of the body to a small dose of ionizing radiation to produce pictures of the inside of the body. X-rays are the oldest and most frequently used form of medical imaging.
Fluoroscopy is a special x-ray technique that makes it possible to see internal organs in motion. During a hysterosalpingogram, the uterus and fallopian tubes are filled with a water-soluble contrast material and the radiologist is able to use fluoroscopy to view and assess their anatomy and function.

Instruments required for hysterosalpingogram (HSG) include an open-sided speculum, tenaculum, sponge stick, antiseptic, contrast medium, and an acorn (Cohen) cannula (A) or a balloon-tip catheter (B).
The cervix is prepared with an antiseptic and grasped with a single-toothed tenaculum. Gentle, slow placement of the tenaculum, grasping only enough tissue for adequate stabilization of the cannula, is recommended. Distress experienced by the patient because of poor tenaculum placement is often a predictor of a negative patient experience. Cohen cannulas come with a narrow acorn tip for use in nulliparous patients or a wider acorn tip for multiparous patients. All air should be removed from the cannula by priming it in the vertical position. Holding the Cohen and applied tenaculum in one hand to occlude the cervix is preferable to attaching the cannula to the tenaculum since it usually causes less pain. A balloon catheter may be more suitable for patients with cervical stenosis since it has a smaller diameter than the tip of the Cohen cannula. Some patients experience discomfort during inflation of the balloon.
In some cases, if certain abnormalities are encountered, the patient will be asked to rest and wait up to 30 minutes so that a delayed image can be obtained. This delayed image may provide clues to a patient’s condition that the original images with contrast material do not. On occasion, an x-ray will be taken the next day to ensure that there is no scarring surrounding the ovaries.
When the procedure is complete, the catheter will be removed and the patient will be allowed to sit up.
When the examination is complete, you will be asked to wait until the radiologist determines that all the necessary images have been obtained.
The hysterosalpingogram is usually completed within 30 minutes.
