A lower GI, commonly known as a barium enema, is an Imaging procedure for the evaluation of the large bowel (colon). A barium enema is used when looking for narrowing, masses, polyps, appendix, or diverticula in your rectum and colon. A certified and trained technologist will gently insert a soft tube into your rectum and give you instructions throughout the procedure. A radiologist will begin filling your colon with barium or a water soluble contrast and will take a series of X-Rays. When the colon is filled with barium, the radiologist is able to view and assess the anatomy and function of the colon.
Your physician will give you detailed instructions on how to prepare for your lower GI. Please inform your physician of any medications you are taking as well as any allergies you may have. Also inform your physician regarding a recent illness or other medical conditions.
Women should inform their physician if they are pregnant, or if there is any possibility they may be pregnant.
Radiation Dose: Special care is taken during X-Ray examinations to use of the lowest radiation dose possible while producing the best images for evaluation.
