Please advise us beforehand

Please make staff aware if

  • you are or think you could be pregnant.
  • you are breastfeeding, claustrophobic and/or if you are the primary/sole carer for small children when you book your appointment.
  • you have had any reactions to injections used for imaging.

Please bring any previous nuclear medicine scans or any other scans relating to the current problem.


No preparation.

How long does it take?

Approximately 1 hour.


You will be required to breathe through a mouthpiece which contains a gas with a radioactive substance to assess the airflow to your lungs. This can take up to 10 minutes. You will then be positioned under a gamma camera which will move around your lungs and take pictures for 15 minutes.

For the second part of the study you will then be injected with a radioactive tracer that will enable further images to be taken to assess the blood supply to your lungs. Images are taken again for a further 10 minutes.

After your examination

It is recommended that you minimise close contact with others (especially babies and small children) for up to 4 hours.

Your images and report

All images for your study will be available on the myPRP patient portal soon after your examination is complete. A report that includes a link to your study will be sent directly to your referring doctor. PRP Imaging will store digital copies of all studies on our secure database for comparison with any future examinations.

Normal and abnormal studies are both important for your management and PRP Imaging encourages you to return to your doctor for review of the results.
