If your doctor has ordered you to have a medical imaging exam, you may have a test that uses contrast dye.
Contrast dye also called medical imaging contrast, or contrast agent is a substance radiologists use that acts like a dye. Contrast dye —sometimes referred to as medical imaging contrast, contrast materials or contrast agent—is a substance that radiologists use to see your organs and tissues more clearly in your medical images.
It can be an iodine-based material, barium-s ulfate, gadolinium, or saline and air mixture that can be swallowed or injected intravenously. Contrast is important because it helps radiologists distinguish between normal and abnormal conditions. In turn, this allows them to make a more accurate diagnosis, and recommend the best treatment for your specific case. In cases where it is needed, contrast ultimately leads to better care.
Contrast can be swallowed as a drink or injected into a vein. It will also determine how it needs to be administered orally or intravenously.
Your body will naturally absorb or eliminate the contrast materials after your exam. Full policy details on when oral contrast is used for CT in the ED.

There are very few indications for rectal contrast in the ER. In the setting of penetrating trauma to the pelvis, rectal contrast may be necessary. To order rectal contrast, order a CT scan as you would otherwise, specify your desire for rectal contrast in the order, and specifically request it when communicating verbally with the ER Radiologist.
What are the contraindications for CT IV contrast? There are two main contraindications for the administration of iodinated IV contrast: contrast induced nephropathy and allergy to iodinated contrast. The attending ER Radiologist and the referring clinician may allow for patients with renal failure to receive intravenous contrast when the risks are felt to be outweighed by the benefits. Read the current policy on renal function and use of Iodinated Contrast Patients who only have one kidney or are kidney transplant recipients can still receive IV contrast as long as renal function is adequate.
See policy details here. Patients who have had a severe anaphylactoid reaction to iodinated contrast should never receive iodinated contrast unless the radiologist and ordering provider are both in agreement that the scan is needed for medical care and benefit outweighs risks. The ED team should be prepared to treat the patient with the radiology team if such a scan is needed and the patient should receive standard Steroid and Benadryl premedication if patients clinical stability allows.
