Positron Emission Tomography - Computed Tomography (PET/CT)

What is it?

PETCT (Positron Emission Tomography Computerised Tomography) is a detailed scan combining a normal Computed Tomography (CT) scan with a Positron Emission Tomography (PET) scan. It is performed on the same scanner all in one appointment.


What does it involve?

The CT scan uses x-ray technology to obtain an image of the body. The PET scan is a type of nucleur medicine imaging, using a small injection of radioactive tracer or dye which travels through the body and is detected by the scanner as the patient passes through it. Different tracers, called radiopharmaceuticals, will localise in different diseases or conditions and provide detailed information of the internal anatomy and function of the body such as blood flow, oxygen use and sugar (glucose) metabolism. Together the scan will create a 3D picture of the inside of the body enabling the consultant to plan a more accurate treatment plan, providing images that pinpoint the anatomic location of abnormal metabolic activity within the body.



PET/CT scan is an outpatient procedure and can be performed to:

  • Detect cancer
  • Determine whether a cancer has spread in the body
  • Assess the effectiveness of a treatment plan, such as cancer therapy
  • Determine if a cancer has returned after treatment
  • Evaluate brain abnormalities, such as tumors, memory disorders, seizures and other central nervous system disorders
