A PET scan produces three-dimensional, colour images which show the tissues inside the body and how they’re working. PET scans are used to check for diseases within the body.
PET scans are commonly used to detect cancer. Cancer cells have a higher level of chemical activity when compared to non-cancerous cells, meaning they show up clearly in a PET scan.
While PET scans are used to detect cancer, they’re also used to see if cancer has spread anywhere else, identify whether a treatment is working, and checking to see if cancer has returned.
The scan works by using a dye containing radioactive tracers. The tracers can either be swallowed, injected or inhaled, dependent on what part of the body is being examined.
PET scans are usually an outpatient procedure, meaning once it’s been completed you can continue with your day as usual.
PET scans can be used for:
- Abdominal imaging
- Breast imaging
- Chest imaging
- Gynaecological imaging
- Prostate imaging
- Musculoskeletal imaging
