What is CT Scanning?

CT scanning—sometimes called CAT scanning—is a non-invasive, painless medical test that helps physicians diagnose and treat medical conditions. CT imaging uses special x-ray equipment to produce multiple images or pictures of the inside of the body. CT imaging is sometimes compared to 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 multi-dimensional view of the body's interior.

What does the equipment look like?

The CT scanner is donut-shaped, with a movable table in the middle.

Radiology Services of New York was the first independent out patient imaging facility in Staten Island to introduce multi-detector technology. This latest technology acquires images many times faster than conventional spiral CT which translate to your maximum comfort and superior quality images.

How should I prepare for the CT scan and what should I expect?

CT exams are painless, fast and easy. You will be asked to change into a gown. Metal objects including jewelry, eyeglasses, dentures and hairpins may affect the CT images and should be left at home or removed prior to your exam.

The technologist begins by positioning you on a comfortable CT examination table, usually lying on your back. Depending on body part being imaged you may be asked to drink a special dye before the procedure or dye may be injected through an intravenous line. Our equipment are especially quiet and you will hear only slight whirring sounds as the CT scanner revolves around you during the imaging process.The CT scanning is usually completed within a few seconds.

After a CT exam, you can return to your normal activities. If you received a contrast material, you may be given special instructions.

If you are receiving intravaneous contrast you should inform us of allergies, prior reaction to CT dye, history of asthma, diabetes or kidney disease.
