helical computed tomography - (pronounced) (HEE-lih-kul kum-PYOO-ted toh-MAH-gruh-fee) A procedure that uses a computer connected to an X-ray machine to create a series of detailed images of areas inside the body to create. The X-ray machine scans the body in a spiral pattern. This means that more images can be taken in less time than with older CT methods. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly on the X-ray. Spiral computed tomography also creates more detailed images and may be better at finding small abnormal areas in the body. It can be used to diagnose diseases, plan treatment, or find out how well treatment is working. Also called spiral CT
