CT Coronary Angiography (CTCA)

CT stands for Computed Tomography, and is also known as a "CAT" scan. It uses X-Rays to produce images of the body. CT Coronary Angiography (CTCA) is a new test to evaluate the coronary arteries. These arteries are on the surface of the heart and supply the heart muscle with oxygen and other essential nutrients. The main advantage of CTCA is that it is non-invasive, meaning no surgical procedure is required. In order to obtain accurate information you need to have a slow heart rate. We ask you to attend Hearts1st at least 1 day prior to your CTCA for a free check of your heart rate. If it is naturally too fast, you will be provided with medication to slow it down. No appointment is required for this check.

Hearts 1st performs CTCA with Qld X-Ray at Greenslopes Private Hospital. Upon arrival at Qld X-Ray your blood pressure and heart rate will be recorded to determine if you need any additional medication to slow your heart rate. Small adhesive dots will be placed on your back where thin leads will be connected to a monitor. This allows us to observe your heart rhythm. A small needle will then be placed into a vein in your arm. This is used for injection of a contrast agent (dye), which will ensure the arteries stand out on the scan. You will lie down on a narrow table that passes through the CT scanner. You will be instructed when to hold your breath during the scan, usually no longer than 10 seconds at a time. It is normal to experience a warm feeling when the dye is injected. The computer then generates up to one thousand pictures of your heart for analysis.

At Hearts 1st and Qld X-Ray, we are aware that any medical examination creates some level of anxiety. The staff will make every effort to ensure you are as comfortable as possible.


Your report will be sent directly to your referring doctor, usually within 24 hours. You do not need to wait for the report or any films, videos or CD’s.
