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.
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 image.
At UVIR we utilize the best technology on the market to produce your images. We have a 64 slice Toshiba scanner which is capable of scanning your entire Chest, Abdomen, and Pelvis in less than 12 seconds! Our Toshiba scanner boasts ultra high resolution scanning, the industry’s thinnest slice configuration, and the best low contrast resolution for lowest dose imaging. This means you get the best image possible with the lowest radiation dose. For those people who enjoy a more relaxed atmosphere, our scanner is located in a spacious, private suite with South facing windows to make the time you are here pleasant. In addition, all of our technologists are registered and extensively trained to provide a safe and superior medical imaging experience.
The CT scanner is a large machine with a hole, or tunnel (called a gantry), in the center. You will lie on a table which slides into and out of the gantry. You may be asked to hold your breath during scanning. The x-ray tube and electronic x-ray detectors which are located inside the gantry rotate around you. The technologist console and the computer workstation that processes the imaging information is located in a separate room, but rest assured that you will be able to communicate with the technologist throughout the scan. A CT examination usually takes five minutes to half an hour. When the exam is over, the patient may be asked to wait until the images are examined to determine if more images are needed.
Sometimes contrast (also referred to as X-ray dye) is needed to highlight bowel structures or internal organs. Contrast can be given orally or through an I.V. 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 Glucophage, Glucovance, or any other medication that includes Metformin, you will need to stop taking it for 48 hours after your exam; your technologist will give you instructions.
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 or drinking anything for up to four hours before the exam. Women should always inform their doctor or x-ray technologist if there is any possibility that they are pregnant.
