What is Computerized Tomography (CT)?
CT is an x-ray examination that uses computers to construct cross-sectional images of the body.
What are the uses of CT?
CT scans show soft tissue densities and structures, and are used for monitoring treatments and while obtaining tissue samples. They can also be used to detect disease such as tumors, infections or blood clots, internal abnormalities such as enlarged lymph nodes or organs and trauma.
Is there any special preparation?
Preparation for a CT scan varies depending upon the specific scan being done. A preparation sheet is available for your specific test.
You may wish to bring along a book or magazine to read while you wait. Schedules are tight and emergencies can cause unexpected delays.
What is involved in the procedure?
Contrast (dye) is often given to enhance certain body part structures. This media is usually given orally or by injection.
You will be positioned comfortably on a narrow, padded table. Your arms will be positioned either by your sides or over your head and your head will be on a pillow or in a head cradle.
As the scan begins, the table will glide into the scanner. Once in position, the technologist who is controlling the procedure from an adjacent room, will talk to you through an intercom system giving you instructions on your breathing technique. As the x-ray equipment scans, you will hear the whirring sound of the machinery. These are normal sounds that may occur. After each scan the table will move slightly.
