imaging procedure that uses x-rays to obtain cross-sectional images of the body. It helps physicians diagnose diseases, tissue abnormalities, as well as monitoring therapies for treating these diseases.
The CT machine looks like a large box with a hole in the center. Unlike MRI, the "hole" or "tunnel" is not very deep and the actual time during the taking of pictures is only minutes. The preparation time takes longer than the procedure itself.
Depending on what study is ordered by your physician, you may be required to drink barium for abdominal and pelvic scans or receive an injection of contrast, or dye, as it is commonly referred to. Barium will fill up your intestinal tract. This will help the radiologist see the lining as well as any growths within the bowel.
The intravenous contrast is given through a needle placed into a vein like a regular IV. The contrast high-
lights vascular structures as well as normal tissue of different organs. It is not radioactive and only stays in
your system for a short time.
When you are brought into the CT suite, the technologist will explain the study to you. There is always a radiologist present in the office to answer any
questions that you may have. Unless you are having a head, sinus or neck CT, you will be going into the machine feet first. More than likely your head will not go into the machine. If you are having intravenous contrast, an IV will be started before the procedure.
As the CT machine takes its pictures you will hear a noise something like a small engine running. The bed will move in and out of the center of the machine. If you are having a chest, abdomen or pelvic CT, you will hear an automated voice ask you to hold your breath. Once this part of the procedure is started, your exam will be over in a matter of minutes. Our Middlebury office is located at 1579 Straits Turnpike and offers CT Scanning as well as MRI, Ultra-
sound and Diagnostic Radiology.
