Computed Tomography (CT) Scan

What is a CT Scan?

A CT scan - also called computerized tomography or just CT - is an X-ray technique that produces images of your body that visualize internal structures in cross-section rather than the overlapping images typically produced by conventional X-ray exams. Conventional X-ray exams use a stationary X-ray machine to focus beams of radiation on a particular area of your body to produce two-dimensional images on film or digital detector, much like a photograph. However, CT scanners use an X-ray unit that rotates around your body and a powerful computer. The result is a set of cross-sectional images, like slices, of the inside of your body.

CT scan of the body is performed to:

• Detect and monitor diseases such as cancer or heart disease
• Detect internal injuries and internal bleeding
• Diagnose muscle and bone disorders, such as bone tumors and fractures
• Pinpoint the location of a tumor, infection or blood clot
