How does Body CT Imaging Work?

Body computed tomography (CT) is a powerful imaging tool used to visualize the chest, abdomen, and pelvis with exceptional detail. The test works by taking multiple X-ray images from different angles around the body, which are then processed by a computer to create cross-sectional images, or slices, of the internal structures. These images provide detailed information about the organs, blood vessels, bones, and soft tissues, helping to diagnose a wide range of conditions.

What are the benefits of Body CT?

One of the key benefits of body CT is its ability to detect and diagnose a variety of conditions affecting the chest, abdomen, and pelvis. In the chest, CT can identify abnormalities such as lung nodules, pulmonary embolisms, and pleural effusions. In the abdomen, CT is used to evaluate the liver, spleen, pancreas, kidneys, and other abdominal organs for tumors, infections, or other abnormalities. In the pelvis, CT can help diagnose conditions such as kidney stones, bladder tumors, and pelvic fractures.

Additionally, body CT is often used to guide procedures such as biopsies, drainage of fluid collections, and the placement of catheters or drainage tubes. It is also valuable in planning surgeries and other interventions, as it provides detailed information about the location and extent of abnormalities. Overall, body CT is a versatile and valuable tool in the diagnosis and management of a wide range of conditions affecting the chest, abdomen, and pelvis.

What happens during the test?

First, the technologist ensures that you have no metal on your body, and reviews your medical history with you. You are then asked to lie on the scanning table, which is moved into the center of the machine, and asked to stay as still as possible to ensure the clearest images. Most exams last only a few minutes, depending on the body part.

The exam is non-invasive and the machine never touches your body. The technologist is available via intercom should the patient have any concerns during the exam.

How do I prepare for a Body CT exam?

How to Prepare

You must remove all jewelry and any other metallic objects such as hearing aids, jeans with metal zippers, body piercings, and removable dental work. Wearing a sweatsuit with no metal may prevent you from having to change into a gown.

Additional prep CT with I.V. contrast

Do not eat anything one hour prior to your exam time. You may drink clear liquids (example: water, ginger ale, apple juice). Keep hydrated before and after your exam.

If you have impaired kidney function, are diabetic, or are 70 years of age or older, we will perform an i-STAT creatinine level at the time of your exam to assess your kidney function. It is important to inform us if you are taking the medication hydroxyurea when making your appointment.

Additional prep CT with oral contrast

If you are receiving oral contrast, please pick up the contrast kit the day before your exam. If you are receiving Omnipaque oral contrast, refer to the Omnipaque oral contrast section below. If you are receiving Redi-CAT oral contrast, please ask your Zwanger-Pesiri representative for those specific instructions.

Omnipaque oral contrast prep for CT scan

Do not take if you have an iodine allergy.

Begin drinking the Omnipaque oral prep one hour and 40 minutes before your exam, preferably finishing 20 to 30 minutes before the exam time.

To prepare the contrast drink:

Pour HALF the contents of the Ominpaque bottle into the 32 oz. cup that was given to you.
Fill the cup with water up to approximately 1/2 inch from the top of the cup (approximately 30 oz).
Stir well and drink.
Discard the cup, contrast bottle and straw after use.
