computerized tomography (noun), CT, CAT scan (s), computerized tomographies (pl)
1. An x-ray procedure that uses the help of a computer to produce a detailed picture of a cross section of tissue of the body.
2. A computerized axial tomography scan which is an x-ray procedure that combines many x-ray images with the aid of a computer to generate cross-sectional views and, if needed, three-dimensional images of the internal organs and structures of the body.

Computerized axial tomography is more commonly known by its abbreviated names, CT scan or CAT scan. A CT scan is used to define normal and abnormal structures in the body and/or to assist in procedures by helping to accurately guide the placement of instruments or treatments.

The procedure was used first in 1972 to study the brain and is a painless and noninvasive procedure that does not require any special preparation. It is considered to be 100 times more sensitive than conventional radiography or X-rays.

As well as being essential for the study of the brain, CT scanning is considered to be invaluable in investigating diseases of any part of the body. It is particularly useful for locating and imaging tumors, and for guiding the operator who is performing a needle biopsy.
