Computed tomography with rectal contrast

How do they do a pelvic CT scan with contrast?
The contrast helps certain areas show up better on the x-rays.
Contrast can be given through a vein (IV) in your hand or forearm.
Or you may be asked to drink a liquid form of contrast.
If contrast is used, you may also be asked not to eat or drink anything for 4 to 6 hours before the test..
How to do a CT scan with contrast?
The most common type of CT scan with contrast is the double contrast study that will require you to drink a contrast media before your exam begins in addition to the IV contrast.
The more contrast you are able to drink, the better the images are for the radiologist to visualize your digestive tract..
What is a CT scan with contrast for the bowel?
What is computed tomography (CT) enterography? CT enterography is an imaging test that uses CT imagery and a contrast material to view the small intestine.
The procedure allows your healthcare provider to determine what is causing your condition..
What is a CT scan with rectal contrast?
Rectal contrast enema provides a safe alternative by optimizing the predictive value of CT interpretation.
Besides the noninvasive nature of CT, it allows for the detection of an alternative diagnosis such as intra‐abdominal abscess and, in case of leakage, the leakage severity and possible preoperative planning..
Why is rectal contrast used in CT scan?

A contrast enema is an x-ray study that uses a water-soluble contrast agent containing iodine or barium to show the structure of the rectum, colon, and large intestine.
Contrast enemas are commonly referred to as barium enemas.
Computed tomography (CT) colonography or virtual colonoscopy uses special x-ray equipment to examine the large intestine for cancer and growths called polyps.
During the exam, the doctor inserts a small tube a short distance into the rectum.
Rectal Contrast Materials
Barium-sulfate contrast materials that are administered by enema (rectally) are used to enhance standard x-ray, fluoroscopy, and CT images of the lower gastrointestinal (GI) tract (colon and rectum).
The oral contrast is used in order to make specific organs “stand out” and better show the presence of disease or injury.
There are a variety of oral contrasts that are used during a CT scan.
Each is used depending on the patient that is being imaged and their specific situation.

Rectal contrast helps to greatly increase the sensitivity of the CT exam. It is important to relax as much as possible until the CT scan is complete. Once the desired amount of contrast has been delivered into the rectum intravenous contrast will then be given at this point if it is also required.

A CT rectal contrast examination is often used to enhance images of the large intestines, but if indicated by the reporting radiologist we may also scan the entire abdomen and pelvis.
