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
