Positron Emission Tomography – Computed Tomography

PET-CT is a dual imaging modality, meaning in one single investigation the radiologist can see both the cellular/metabolic function (how the cell works), as well as the anatomy (what it looks like). It is also a whole-body imaging modality, enabling us to look at the entire body with a single investigation

PET, in particular, is a type of molecular imaging. Molecular imaging allows us to see how the body is functioning at a cellular level and enables measurement of its chemical and biological processes. PET involves using a small amount of (intravenously injected) radioactive substance, known as a radiopharmaceutical, to form a functional image of tissues within the body. The PET camera is used to detect the radiation that is emitted from the radiopharmaceutical in your body, and this information is used to convert the detected activity into an image. When it is combined with CT it is called a PET-CT. We use the CT component to ensure accurate localisation of the uptake seen on the PET. 

In some instances PET can detect early onset of disease (like the spread of cancer) before it is evident on other imaging modalities. PET may be used to assess whether treatments regimes are working, as well as to distinguish between scar tissue on a treated tumour and active tumour cells. A PET-CT Scan plays a specific role in the management of disease, and does not replace a CT, MRI or other anatomical image. Information gained on these scans complement each other.
