CT Coronary Angiography Explained: Prep, Procedure & Care
CT Coronary Angiography: Scan to View Heart Arteries & Chambers
A contrast dye is used to assist during this scan.
A CT scanner is a circular machine that uses low dose radiation x-rays to produce images of various part of your body. Lying on a movable platform you will be moved into the machine along a track to the correct position for the area to be scanned.
The purpose of CT coronary angiography is to review the heart for any evidence of fat or calcium deposits, narrowing of the arteries and to overall assess the function of the muscle and valves of the heart.
During the hour prior to your CT coronary angiography you will be asked your medical history and to complete some required paperwork.
Your heart rate will be checked, and if it is above 60 beats a minute, you will be given a beta blocker medication to lower it for the purposes of the test.
You will be asked to change into a gown, and have a cannula inserted so the contrast can be administered.
Once the contrast is in your system and your heart rate is within the require range the CT coronary angiography will begin.
During the procedure you may be asked to hold your breath as the scans are taken.
If you were given beta blockers for the procedure, your blood pressure and heart rate will be monitored to ensure they are normal prior to your departure.
You may receive some post exam instructions to follow after the CT coronary angiography.
It is important to drink plenty of fluids after the procedure.
Your CT coronary angiography results will be reviewed by a specialist and the report will be sent to your referring doctor. It is best to make an appointment with them to follow up on the results.

Is a CT coronary angiogram painful?
A CT coronary angiogram is generally not painful. Most patients experience only mild discomfort from the intravenous contrast dye injection, but the procedure itself is quick and well-tolerated.
How often should I have a CT angiogram?
The frequency of having a CT angiogram depends on individual health factors and your doctor's recommendations. Generally, it may be advised every few years or as needed to monitor heart health, especially if you have risk factors for cardiovascular disease.
What are the alternatives to CT coronary angiography?
The alternatives to CT coronary angiography include traditional coronary angiography, which involves catheter insertion, as well as non-invasive tests like stress tests, echocardiograms, and magnetic resonance angiography (MRA) for assessing heart health.
Can a CT angiogram replace traditional angiography?
A CT angiogram can complement traditional angiography but does not fully replace it. While it provides detailed images of blood vessels and can assess heart health effectively, traditional angiography remains essential for certain diagnostic and interventional procedures.
What is the recovery time after a CT scan?
The recovery time after a CT scan is typically minimal, as most patients can resume their normal activities immediately. If contrast dye is used, some may experience mild side effects, but these usually resolve quickly.
How does a CT coronary angiogram differ from an MRI?
A CT coronary angiogram differs from an MRI in that it uses X-ray technology and contrast dye to visualise blood vessels and assess heart health, while MRI employs magnetic fields and radio waves to create detailed images of the heart and surrounding structures.
What is the purpose of a CT coronary angiogram?
The purpose of a CT coronary angiogram is to create detailed images of the heart's blood vessels, helping to assess coronary artery disease and identify any blockages or abnormalities that may affect heart health.
