WHAT IS COMPUTED TOMOGRAPHY (CT) AND HOW DOES IT WORK?
A Computed Tomography (CT) scan is a precise, simple and noninvasive examination that creates a cross-sectional image of a specific anatomical part of the body. A thin beam of x-rays is emitted and recorded by an electronic detector, then transferred into a computer. The computer constructs an image based on the data, which is then transferred to film. Contrast media, commonly referred to as “dye” or barium, is sometimes given, intravenously, orally, or rectally before and/or during certain scans to assist in viewing a particular area.
