CT scanning. Doctor overseeing the computed tomography (CT) scanning of a patient (upper left) from a control room. CT scanning uses X-rays to take slice images through the body (as seen on the monitor at upper right). Several slice images can be combined to create a three-dimensional (3-D) image,such as the one on the monitor at centre left,which shows an atheroma plaque blocking an artery. These 3-D views can be used to study the interior structures of the body without using invasive techniques. CT scanning is useful for detecting tumours in organs and can also be used to study smaller areas in detail,such as the insides of arteries | |
