Coloured computed tomography (CT) and positron emission tomography (PET) composite scan of the axial section through a normal chest. CT scans provide detailed images of the body’s internal structures, such as bones, organs and tissues. PET scanning using radioisotopes shows variation in metabolic activity in the body's internal organs which is often indicative of cancerous cells because they consume more glucose than normal cells. | |
