It's often used to detect the following:

  • lung cancer
  • brain cancer
  • breast cancer
  • ovarian cancer
  • colorectal cancer
  • lymphomas
  • melanomas and multiple melanomas.

Need to know

Your FDG PET scan will be carried out by one of our specialist technicians at one of our outpatient centres. After explaining the scan, they'll give you an intravenous injection of a fluorodeoxyglucose, a radioactive tracer.

You'll then be asked to wait for up to two hours for the tracer to be absorbed fully. After the tracer has set in, you'll be asked to lie flat on your back. Your technician will then use a nuclear medical scanner to take photos of the inside of your body. The radioactive tracer will help to show up your internal organs in detail. The scan will take about an hour.

You'll be asked to avoid eating anything for six hours before your scan. You may also be asked to limit your drink intake.

You'll be able to go home straight after your FDG PET scan. The results of your scan will be sent to your HCA UK GP or consultant. They'll discuss the results with you and let you know if you require any further tests or treatment.
