What is a PET-CT scan?

PET-CT scans combine PET (positron emission tomography) and CT (computised tomography) technology in one full body scanner.

This advanced nuclear imaging technique where tracers shows how the cells in the body are functioning at the same time as generating 2D and 3D images of inside the body.

How does a PET/CT scan work?

PET-CT scans can be used to diagnose, and monitor cancer to see if cancer has spread to other parts of the body. It is also used to assess the body's response to treatment. This scanner is increasingly used to diagnose inflammatory conditions and heart conditions. 

For the PET part of the scan, you'll be given an injection of a substance called a radioactive tracer. As this is absorbed by the body, any cancerous or inflammatory cells will show up on the scan as hot spots. The CT scan produces 2D X-ray images of your body as it moves through the scanner. These can be layered to create 3D images for your consultant to analyse.

Like all procedures, there may be some risks and side effects involved. These will be explained to you, and your consultant can answer any questions you have.

Other nuclear medicine scans

Nuclear medicine scans are common diagnostic tests that use tracers to investigate the body in more depth. Scan include bone scans, lung scans and certain tests for heart, thyroid and kidney function.

SPECT-CT scan

Single Photon Emission Computed Tomography scan is a type of nuclear medicine imaging scan using radioactive tracers combined with CT imaging.

SeHCAT scan

A scan to check how well your gut absorbs bile salts. It is used to investigate a range of conditions including irritable bowel syndrome (IBS) or chronic diarrhoea.


FDG PET scan

A FDG PET scan is one of the more common nuclear medicine scans, used to assess the metabolic activity of certain tumours. It can also be used to stage a disease, or monitor the body during treatment.

Thyroid scan

A diagnostic scan using tracers to investigate the function of the thyroid.

Myocardial perfusion scanning

Myoview™ or nuclear stress test. A myocardial perfusion scan looks at blood flow patterns to the walls of the heart both during exercise and at rest
