  • Radiotherapy Planning CT Explained

    When using Radiotherapy in the treatment of cancer, it is important to gather as much information about the cancer as possible. This is where the Radiotherapy Planning CT comes in. It will show the cancer and the structures around it, allowing your Doctors to plan treatment that exposes as little of normal tissue and as much of the cancer as possible.

  • Please advise us beforehand

    If you have had an adverse reaction to a previous contrast injection or other drugs or if you have any renal impairment. We will ask you to complete a questionnaire before the examination and sign a consent to the contrast injection if it is required for your examination.

    Please advise us if you are, or think you may be, pregnant.

    Please bring your referral, Medicare and Pension Health Care Cards with any previous imaging relating to the region being scanned.

  • Preparation

    No preparation is required.

  • What happens during the procedure

    You will lie down on the scanner couch with the treatment area exposed. The radiographer will put some markers on your skin (these show up on the scan as white dots) and are used to take measurements to plan your radiotherapy treatment. You will then have your images taken. Once these are finished, they will give you small permanent dots on your skin which are used to position you correctly each day when you have your radiotherapy.

    You may also have to;

    • Have an injection of dye to show your kidneys.
    • Have wires places on lumps or scars.
    • Drink liquid with dye to how your bladder.
    • Drink barium liquid to show your oesophagus and/or stomach.

    Dependent on where your cancer is, you may need a mould or mask created.

  • How long does it take

    The actual CT scan takes around 30 minutes, though the session itself may take longer.

    You may need more than one planning session.

  • After your examination

    If you have had contrast, you’ll need a high fluid intact for 24 hours to help flush your system.

  • Your images and report

    As there is a large amount of data to be processed, your results will not be ready straight away. We will advise you at the completion of your appointment when they will be delivered to your referring Doctor.

    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.
