Cardiac CT scan

CT coronary angiography

High-resolution 3D images of the moving heart, coronary arteries and great vessels

About

A computed tomography (CT) coronary angiography is a test that combines a conventional CT scan with a traditional angiography to check if any of the coronary arteries supplying blood to your heart have narrowed or are likely to become blocked. It's a less invasive alternative to a traditional catheter angiography.

Need to know

  • What happens icon plus

    A radiologist will carry out a pre-procedure assessment to check your heart rate. They may give you an intravenous beta-blocker to slow it down. To see the arteries clearly, we'll use an X-ray contrast dye, which will be given through an injection in your arm. We'll then ask you to lie on the couch while the CT scanner passes over you several times. This takes a number of X-rays known as 2D 'slices.' These can be combined to form a detailed 3D picture of your heart and arteries. During the scan we'll monitor your heart using an electrocardiogram (ECG). Your CT coronary angiogram is an outpatient procedure and takes about 15-20 minutes.
  • How to prepare icon plus

    Your consultant will let you know what you need to do leading up to your CT scan. You'll probably be asked to avoid all forms of caffeine for 12 hours prior to the study. A prescription of tablets, usually beta blockers, to slow down and regulate your heart rate ahead of the your scan is also common.
  • Afterwards icon plus

    Your radiologist will review the results and send them to your consultant. You'll be able to go home straight afterwards unless your procedure involves intravenous beta blockers, in which case you'll be monitored for around 45 minutes afterwards. You shouldn't drive for three hours after the CT scan and avoid operating heavy machinery for the following 24 hours.
