CT Coronary Angiogram

A CT scan is a specialised x-ray that allows detailed pictures to be taken of parts of the body in order to diagnose certain conditions. A CT Coronary Angiogram (or CTCA) takes detailed CT images of the coronary arteries which are the blood vessels that supply blood to your heart muscles. The test looks for any potential narrowing or blockages which may be causing some of your cardiac symptoms.


CT Coronary Angiogram

A CT Coronary Angiogram looks at the condition of the coronary arteries (blood vessels) that supply blood to your heart. If these arteries are blocked or narrowed, then you might experience symptoms such as chest pain or shortness of breath because your heart cannot get the amount of oxygen it needs.

The test involves some contrast dye to allow for the arteries to be seen clearly. On the day of your scan, you will be asked to avoid caffeine and you may be given some medications before the test to control your blood pressure or heart rate if necessary. The contrast dye will be inserted through a small needle (cannula) which is usually placed on the arm. During the test, small amounts of dye will travel through the cannula into the bloodstream and up to the heart to 'illuminate' the arteries. This is completely harmless, and the dye will leave the body naturally as any other liquid.

Once the cannula has been inserted and the blood pressure and heart rate checked, you will be asked to lay down on a scanning bed which will be attached to the CT scanner (which is a donut shaped machine). The staff will then guide the bed into the scanner and the test will commence. The staff will be required to be in another room during the scan to minimise any radiation, but you will be able to speak to them throughout the test. You will not be in the scanner for any more than 15-20 minutes after which you may be asked to stay for some observation to ensure that your heart rate and blood pressure remain at normal levels, after which you should be able to go home. The results of the scan will be passed to your doctor/GP, which may take a few days.
