What Is a CT (CAT) Scan?
Computerized Tomography (CT) provides cross-sectional images of any body part. Cross-sectional images are often described as looking into a loaf of bread by cutting the loaf into thin slices. When the image slices are reassembled by computer software, the result is a very detailed multidimensional view of the body’s interior used to assist in the diagnosis of conditions of organs and body structures.
How CT Works
Computerized Tomography (CT) is a special type of x-ray that rotates around your body 360 degrees forming a multi-dimensional set of data that can be viewed in multiple planes. CT scanning produces detailed images not produced by ordinary x-rays because the CT scanner uses a very thin beam of x-ray and a computer to generate and manipulate the image.
CT is Ideal For
What to Expect
The CT scanner is a machine with a hole, or tunnel, in the center. You will lie on a table which slides into and out. You may be asked to hold your breath during scanning; this helps eliminate motion providing a better image. The x-ray tube and electronic x-ray detectors which are located inside the tunnel rotate around you. A CT examination usually takes five minutes to half an hour.
Sometimes contrast (also referred to as X-ray dye) is needed to highlight bowel structures or internal organs. Contrast can be given orally or intravenously. Contrast used for CT is iodine based, if you have ever had an allergic reaction to Iodine or X-ray dye, please notify your technologist. If you take any diabetic medications notify the scheduler, you may need to stop taking certain medications prior to your CT scan.
How to Prepare for the Study
You should wear comfortable, loose-fitting clothing for your CT exam. Metal objects can affect the image, so avoid clothing with zippers and snaps. You may be asked to remove hairpins, jewelry, eyeglasses, hearing aids and any removable dental work that could obscure the images. You also may be asked to refrain from eating anything for up to four hours before the exam. Women should always inform their doctor, scheduler, or x-ray technologist if there is any possibility that they are pregnant.
****You may take any necessary medications prior to your exam with a small amount of clear liquid, if your medication requires food be taken with it, please contact us prior to your exam*****
