You may be asked to drink a special oral contrast material or plain water 1-2 hours before the exam to improve visualization of your intestines and or be given an IV injection of Iodinated contrast material during your exam.
Please inform your referring Doctor before your scan if you have any allergy to Iodinated Contrast material so accommodations can be made or an alternate test be considered. Patients who have diabetes or renal disease require special care because the kidneys are involved in filtering the iodine from the bloodstream. These patients should consult with their physician about proper scheduling of the CT scan.
You should wear comfortable, loose-fitting clothing for your CT exam. Metal objects can affect the image, so avoid clothing with zippers and snaps. You may also be asked to remove hairpins, jewelry, eyeglasses, hearing aids and any removable dental work, depending on the part of the body that is being scanned. You may be asked to change into a gown.
