CT angiography, including coronary CTA

What is a CT angiogram?

It is a CT scan performed while a contrast dye flows through your blood vessels, so they stand out clearly in the images. Coronary CT angiography focuses on the arteries that supply the heart muscle.

Why your doctor may request it

Your doctor may request a CT angiogram to help assess:

• The coronary (heart) arteries
• Arteries of the neck and brain
• The aorta
• Arteries of the limbs or kidneys

What to expect

A small cannula is placed in a vein for the contrast. You may feel a brief warm sensation when it is injected. For coronary CTA you may be asked to hold your breath, and the team may need to check your heart rate before scanning.

Before your visit

• Our staff will ask about your kidney function and any allergy to contrast.
• Tell us about your current medicines, especially diabetes and heart medicines.
• Tell us if you are or might be pregnant.
• Bring your doctor's request, your insurance card and any previous tests.
• Our team will confirm your instructions when you book. [PREPARATION NOTES]
