PET (or Positron Emission Tomography) is a branch of nuclear medicine imaging that uses special radio-active materials (positrons), in conjunction with a low-dose CT scan, to produce three dimensional images of the body.

PET is a very specialised imaging technique that has various roles including: aiding in the detection of cancer, staging cancers prior to surgery, monitoring the response to chemotherapy and also detecting the recurrence of tumours.

It is most commonly used for tumours like lymphoma, melanoma, bowel and oesophageal cancer and head and neck tumours but can be useful in a wide variety of other tumours and occasionally heart and brain imaging.

Important information

The radioactive tracer used for PET scans is delivered on a daily basis. Due to it's short active life, variables in manufacture and possible delays in transport which are beyond our control, we are unable to confirm scan times until the day before the appointment. Therefore, we need to be able to contact you at any time of the day before and the day of the appointment. If you miss your appointment time (or are late) we may have to reschedule your scan on a later day.
