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
