  • V/Q Lung Scan Explained

    Also known as: Lung scan, V/Q, Ventilation/Perfusion scan.

    A V/Q Lung scan is performed to assess the air flow and blood flow within your lungs to diagnose (and follow up) blood clots (also known as PE’s).

  • Please advise us beforehand

    Please make staff aware if you are (or think you could be) pregnant, breastfeeding, claustrophobic and/or if you are the primary/sole carer for small children when you book your appointment.

    Bring any previous Nuclear Medicine scans or any other scans relating to the area of interest.

  • Preparation

    Eat and drink as normal before and after your scan.

  • What happens during the procedure

    Part 1: You will be asked to inhale a slightly radioactive gas through a tube. This takes approximately 5 minutes and shouldn’t make you feel any different. Images of your chest will then be taken for the next 10-15 minutes.

    Part 2: Next, a small injection of a radioactive tracer is administered which allows imaging of the blood flow to the lungs. This injection shouldn’t make you feel any different. Additional images are acquired, taking a further 10-15 minutes to complete.

  • How long does it take

    This scan takes approximately 45-60 minutes to complete.

  • After Your Examination

    Eat and drink as normal before and after your scan.

    Resume normal activities (including driving) following your examination.

  • Your images and report

    We will advise you when your images and report will be ready. PRP will store digital copies of all studies on our secure database for comparison with any future examinations.

    Please bring any previous images with you for comparison.

    It is important that you return to your doctor with your examination results. Whether they are normal or abnormal, your doctor needs to know promptly so that a management plan can be formulated.
