These procedures are offered at all three hospitals locations.¬† The procedures require an examination by the radiologist with a fluoroscope, a “live” x-ray which allows observation of portions of the body which may not be satisfactorily evaluated by static or plain x-rays.

Common procedures include upper gastrointestinal series (UGI) for the esophagus, stomach, and duodenum, or barium enema (BE) for the colon.

Myelograms are performed by injecting a water soluble fluid into the cerebrospinal fluid (CSF) in the spine and taking x-rays.  Arthrograms for the wrists, shoulders, knees, ankles, and elbows require fluoroscopy to guide contrast injection into the joints.

Hysterosalpingograms (HSG) evaluate the female reproductive tract and require fluoroscopic observation for optimal performance and safety.


UGI and BE require restricting intake of fluids and food beginning at midnight prior to the exam. Check with the department performing the exam for other preparation for BE the evening prior to the exam.

If both UGI and BE have been requested, performing the BE first, then the UGI 48 hours later is recommended for the best exams.

Arthrograms and HSG require no preparation, although HSG should be performed 10 days or less following the first day of the last menstrual period.

Hysterosalpingogram (HSG)

These procedures are offered at Houston Northwest Medical Center Hospital, Cypress Fairbanks Hospital, and CAT Scan Center (Woodlands Office). Fee is sometimes covered by insurance.

This is an x-ray of the female's cervix, uterus and fallopian tubes done in order to determine if both fallopian tubes are open. The test is done much like a pelvic examination where a small tube is inserted into the cervical canal. Then contrast fluid is injected and several x-rays are taken as the material flows through the uterus, tubes and into the pelvis. This test is usually done on CYCLE DAY 8-10, but should be performed by the cycle day 10.
