computed tomography scan
Pronunciation: (kum-PYOO-ted toh-MAH-gruh-fee skan)
A procedure that uses a computer linked to an x-ray machine to make a series of detailed pictures of areas inside the body. The pictures are taken from different angles and are used to create 3-dimensional (3-D) views of tissues and organs. A dye may be injected into a vein or swallowed to help the tissues and organs show up more clearly. A computed tomography scan may be used to help diagnose disease, plan treatment, or find out how well treatment is working. Also called CAT scan, computerized axial tomography scan, computerized tomography, and CT scan.
