Contrast Agents: Ensuring A Clearer Picture

Many CT Scans require the use of contrast agents (also often referred to as dyes) to increase enhancement of certain organs. These contrast agents come in two forms: Oral and Intravenous (IV) contrasts. Certain CT Scans require the use of both oral and IV contrast for enhancement, while other scans require one or the other.

Oral contrast is often necessary when imaging the stomach, small bowel and colon in order to better distinguish these organs from other anatomy within the abdomen and pelvic region. If your Dr. has scheduled you for a CT Abdomen or CT Abdomen & Pelvis that requires you to drink oral contrast you may stop by our office which is located on Nationwide Drive and pick up your oral contrast prior to your appointment. Oral contrast can be picked up at our front desk between the hours of 7:30am-6:30pm.

Intravenous (IV) contrast is administered thru an IV injection and is often necessary to highlight the vascular structure being imaged. With the use of IV contrast some patients will experience a warm flush feeling and a metallic taste. This is normal and passes relatively quickly. Patients are encouraged to drink 64 ounces of fluid following IV enhancement.

Prior to receiving IV enhancement please let the technologist know if you:

1. Are allergic to any medications or iodine.
2. Have a history of diabetes, kidney problems, asthma or a heart condition.

Some patients experience adverse reactions from IV contrast injections.

Please inform the technologist if you:

1. Experience itching or hives after receiving the IV contrast. (Most patients will see these symptoms before they leave.)
2. Become short of breath, experience difficulty breathing or swelling of the throat. These indicate a more severe reaction to the IV contrast agent and may require immediate treatment.
