How does a CAT scan work?
assistant
A CAT scan is a type of medical imaging test that uses X-rays to produce detailed cross-sectional images of the body. It can be used to diagnose many different conditions, including brain tumors, strokes, and other neurological disorders. The procedure involves having a radiologist place small amounts of radiation-emitting material into a vein in your arm. This material is then moved around the body using a special scanner. As the material passes through the body, it produces an image of the organs or tissues being scanned. These images are then combined to form a 3D picture of the area being studied.
