Computed Tomography (CT) Scans and Cancer
What is computed tomography?
Computed tomography (CT) is a noninvasive imaging procedure that uses special x-ray equipment to create detailed pictures, or scans, of areas inside the body.
Each picture created during a CT procedure shows the organs, bones, and other tissues in a thin “slice” of the body.
The entire series of pictures produced in CT is like a loaf of sliced bread—you can look at each slice individually (2-dimensional pictures), or you can look at the whole loaf (a 3-dimensional picture). Computer programs are used to create both types of pictures.
Modern CT machines take continuous pictures in a helical (or spiral) fashion rather than taking a series of pictures of individual slices of the body, as the original CT machines did.
Helical CT (also called spiral CT) has several advantages over older CT techniques: it is faster and produces better quality 3-D pictures of areas inside the body, which may improve detection of small abnormalities.
CT has many uses in the diagnosis, treatment, and monitoring of c
