Coloured computed tomography (CT) and positron emission tomography (PET) composite scans of the axial (left) and coronal (right) sections through a healthy head (left) and healthy 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. | |
