Definition:
A CT scan (sometimes called a CAT scan) allows for a detailed image to be taken of the internal tissues of the body. CT is an abbreviation that stands for "computed tomography." In fact, a powerful computer works to put together the large amount of information obtained by this test into a detailed picture of the body.
CT scans use x-rays aimed from multiple, different points around the patient to obtain their images and, therefore, expose the patient to some radiation.
