CT

Computed Tomography (CT), also commonly referred to as a CAT scan, is a medical imaging method that provides detailed 3-D images of areas inside the body. CT uses a thin beam of x-rays to take a series of cross-sectional pictures of specific organs or areas inside the body from multiple different angles. The CT’s computer then analyzes the pictures and constructs a three dimensional image of the area of interest. During some CT scans, a contrast medium, or “dye”, is used to outline blood vessels or highlight organs of the body so that they can be seen more easily.
