What is a Cardiac CT?
A cardiac CT is a coronary angiogram that is a specialised form of CT (Computed Tomography), that is able to show the arteries around the heart. We can assess for any disease building up in these arteries, which can result in a heart attack or stroke.
Our machine at Vision Radiology, is cutting edge and is the only one of its kind in private practice. It uses Artificial Intelligence (AI) to reduce the dose of radiation used along with the background noise resulting in a far superior diagnostic image.
What happens during my CT coronary angiogram?
CT coronary angiography is a specialised form of CT (Computed Tomography), that is able to show the arteries around the heart. We can assess for any disease building up in these arteries which can result in a heart attack or stroke.
Our machine at Vision Radiology, is cutting edge and is the only one of its kind in private practice.
We use CT scanning to take pictures of the coronary arteries of the beating heart. These arteries supply blood to the heart muscle, and disease of these vessels (atherosclerosis) is responsible for most heart attacks.
A liquid contrast agent, sometimes called contrast medium is injected into a vein (usually in the arm). Contrast agents increase the density of the blood in the vessels, and allow the inside and outside structure of blood vessels to be clearly visible on the CT angiogram images.
Medication to reduce blood flow and slow down the heart rate might also be given to make the images even clearer and easier to interpret. This will either be given in tablet form or into a vein through a cannula (a thin plastic tube) inserted in the arm.
Do I need an appointment?
You do need to come in or call us over the phone to make an appointment for this test.
How much does the CT coronary angiogram cost?
At Vision Radiology we pride ourselves on our ability to deliver first class services within the health system using Bulk billing methodology. This means that your Cardiac CT will be bulk billed if you have your medicare card and a practitioners referral with you, and you will have no out of pocket expenses.
Can I use my referral anywhere?
Yes, we can accept any other radiology referrals. If in doubt please seek advice from our friendly reception staff.
How do I prepare for my CT coronary angiogram?
Firstly you will need a referral from your doctor or medical specialist, and an appointment with us for the test.
One of our staff members will then contact you in regards to what you will need to do to prepare for the examination. Please advise our staff if you are diabetic.
On the day of the scan
Nothing to eat or drink for 4 hours before the scan. No smoking, physical exertion or alcohol.
The images are clearer if your heart rate is low, and you might be given medications before the test to slow down your heart rate. It is advisable that you do not have any tea (including herbal teas), coffee, cola or other stimulants before the procedure as these contain caffeine, which can raise your heart rate.
If you are taking metformin for diabetes, you may or may not need to stop taking it for this test, depending on whether or not your kidney function is normal. You will need to bring the results of a recent kidney function test with you, so that it can be checked by our staff.
Please let our staff know of any history of a reaction to x-ray contrast.
The scan itself will require us to insert a small cannula into your arm, so that we can inject the x-ray contrast.
The scan time is very quick. The preparation along with the time you will wait once the scan is finished may take up to 1 hour all together (you will wait with us for approx. 30 minutes once you have finished being scanned).
