CT Abdomen/Pelvis

CT (Computed Tomography) scan, also known as a CAT Scan, provides the radiologist with detailed images of the organs and deep parts of the human body. It uses a rotating x-ray device and a computer to create an image through the human body, similar to how a slice of bread shows us what the inside of a loaf of bread looks like.

The patient is placed on a slowly moving CT table and the patient moves through the scanner, which is designed more like a doughnut than a tube and is only 36 inches deep. Most claustrophobic patients find the visit to be very manageable. The total time where the patient is engaged with the scanner itself is about 5 minutes.

All patients should expect that the radiologist, who will interpret the exam, might suggest the use of x-ray dye or x-ray contrast material, which is given through a small IV, into the bloodstream. The technologist will explain the specific requirements for your scan prior to your study. Please feel free to ask any questions.

Patients should expect that they will be required to drink 3 - 4 (7 oz.) cups of a dilute citrus flavored barium liquid. This process is the longest part of the exam time and on average is 45 - 90 minutes prior to the scan.

If this scan is being performed because of an abnormality found on another imaging study, the patient should bring those films and the report with them at the time of their CT scan.

Preparations:
    1. No food or drink for 4 hours prior to exam time. Medications may be taken with a small amount of liquid up to exam time. Patients who are diabetic should call the CT Department if they need to eat prior to the study due to insulin, etc.
    2. Patients who are diabetic and are on Glucophage should not take Glucophage on the day of the exam and should consult their physician before restarting the medicine.
    3. Patients should wear comfortable, loose fitting clothing and will be required to remove any articles of clothing or jewelry, which may interfere with the CT Scan such as belts, pocket change or bras.

Precautions:

    1. Patients should inform the technologist if they have a history of allergies (especially to previous contrast injections, medications, or shellfish), asthma, diabetes, kidney problems, thyroid problems, or heart conditions. Please inform the technologist if you are or may be pregnant.
