What is a CAT scan?

A CAT scan, also known as a CT (computed tomography) scan, is a medical imaging procedure that uses X-rays and computer technology to create detailed cross-sectional images of the body. It provides more information than standard X-rays and is commonly used to diagnose diseases, detect injuries, and guide certain medical procedures. CAT scans can be performed on many parts of the body, including the head, chest, abdomen, and spine. The procedure is generally quick, non-invasive, and painless, although some scans may require a special dye called contrast material.
