Patient Information

Positron emission tomography–computed tomography (PET-CT) is a global best practice diagnostic imaging tool that captures three-dimensional images of the body's biological functions. By utilising a small amount of a radiotracer (a radioactive substance that is used in medical imaging*), PET-CT scans can detect areas of abnormal metabolism or function in the body, including fast-growing cancers and infections. ​

​PET-CT scans help doctors pinpoint the location of tumours or cancerous lesions, assess the extent of disease, determine whether lesions are benign or malignant, and identify any potential spread. ​

​PET-CT provides oncologists with accurate information on the extent and severity of disease which enables them to better plan a patients cancer management and treatment, avoiding over or undertreatment, and potentially improving patient outcomes. 

 *Radiotracers are administered in controlled doses and do not contain dangerous levels of radioactive substances
