During the Procedure:
A registered technologist(s) will perform the procedure following the directions of a doctor (Radiologist). Please feel free to ask any questions at any time during your procedure.
A technologist will go over some medical history and your medication list with you prior to the procedure. She/he will explain to you what your procedure requires. You will be positioned on your back on a flat table with a pad.
A technologist or nurse will start an IV for the administration of contrast dye. One or two x-rays / tomograms (where the x-ray tube moves in sync with the film) of your abdomen will be obtained. The technologist will show the image(s) to the radiologist. The radiologist will provide the technologist with the amount of contrast dye to give you, what images to take, and when.
Please note the contrast can make you feel the following normal sensations: the urge to urinate, warm or flushed in the throat and/or pelvic area, wave of nausea or experience a metallic taste in your mouth. These feelings should pass a few minutes after the injection.
Once all the contrast has been administered, a series of x-rays will be taken, including tomograms. These images are timed and there will be some waiting in between.
The technologist will show all of the x-rays to the radiologist and if there are no more x-rays to be taken, you will be shown to toilet facilities to empty your bladder then another final x-ray will be taken.
Once the procedure is complete, the technologist will provide discharge instructions in both verbal and in written form. You will be escorted to the changing room to dress and then out of the department through reception.
The radiologist (doctor) will read the images and dictate a report. Your physician will receive a report of the findings within 2 business days and should advise you of the results. Be sure to follow the discharge instructions given to you after your procedure.
***Important*** Drink plenty of water (8-10 cups/day) for a few days following the procedure to flush the contrast dye. The contrast dye is colorless and leaves the body as you urinate.
