Cardiac CT Scan

The Prince Charles Hospital Medical Imaging department is renowned for its quality cardiothoracic imaging service, which includes cardiac computerised tomography (CT). In collaboration with the Heart Lung Institute, we use specialised imaging techniques to take comprehensive x-rays of the heart. These x-rays can be used to reproduce detailed 2D, 3D and functional images to assess the structure of the heart and how it beats, while still keeping radiation dose to a minimum. This can assist in the diagnosis of chest pain, shortness of breath and help assess known cardiac and vascular issues.

Frequently asked questions

It can take between 10 minutes and 2 hours depending on what part of the body is being scanned.

  • You may need to take medication provided by us when you arrive to control your heart rate for the scan, depending on what imaging is being performed.
  • You will be asked to lie still on a table. The radiographer will not be in the room during the scan, but they will be able to see you and communicate with you at all times.
  • During the scan, you will hear a whirring or humming noise (like a noisy washing machine) and you will feel the table move through the CT scanner. You should remain as still as possible, as the slightest movement can blur the pictures.
  • For some scans, you will be asked to hold your breath for a short period.

You will sometimes be given contrast as part of your CT scan.

  • Contrast allows your heart and vessels to be seen more clearly on x-rays.
  • If required, contrast will be given as an injection (Iodinated contrast).
  • A fine needle (IV cannula) will be put into a vein in your arm, making it possible to inject intravenous contrast.
  • For more information on iodinated contrast and the risks involved in its use, please read the Iodinated Contrast Patient Information Sheet.

You can eat and drink normally after your CT scan is finished. We may need to observe your heart rate and blood pressure for a short period after your scan.

Your CT scan results will be sent to your doctor.

The amount of radiation you will receive will be dependent upon the specific examination your doctor has requested for you. If you have any concerns regarding this examination, you should discuss it further with your doctor as the benefits should outweigh the risks to you.
