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
