What is a CT Coronary Angiogram?
A CT Coronary Angiogram is a specialised CT scan that creates detailed 3D images of your coronary arteries. Unlike traditional invasive angiography, CTCA uses X-rays combined with computer technology and intravenous contrast dye to reveal any blockages or abnormalities in your heart’s blood vessels.
Who Should Get a CT Coronary Angiogram?
A CT Coronary Angiogram (CTCA) is a non-invasive imaging test used to evaluate the coronary arteries—the blood vessels that supply the heart. It helps detect blockages or narrowing due to plaque buildup. Doctors may recommend this test for individuals in the following situations:
Chest pain or angina of unclear cause
If you experience chest discomfort or tightness and routine tests fail to identify the cause, a CTCA can help determine if coronary artery disease is contributing to your symptoms.
Suspicion of coronary artery disease (CAD) but low-to-moderate risk
CTCA is especially useful in patients who are suspected of having CAD but don't have major risk factors. It helps rule out significant artery blockages without the need for an invasive procedure.
If your exercise or chemical stress test results are inconclusive or show irregularities, a CTCA can provide a clearer image of your coronary arteries to support diagnosis and treatment planning.
Pre-surgical cardiac evaluation
Before undergoing certain surgeries—especially those involving the heart or major vessels—your doctor may order a CTCA to assess your heart’s condition and minimize perioperative risks.
Monitoring known coronary artery disease progression
Patients already diagnosed with CAD may undergo periodic CTCA scans to monitor disease progression, evaluate treatment effectiveness, or decide on future interventions.

CT Coronary Angiogram Procedure
A CT Coronary Angiogram (CTCA) is a specialised, non-invasive imaging test that uses a high-speed CT scanner and contrast dye to create detailed pictures of the coronary arteries. It helps doctors assess the presence of blockages, narrowing, or plaque buildup that may lead to heart problems. Unlike traditional angiography, CTCA does not require inserting a catheter into the heart, making it safer and more comfortable for patients. The entire procedure is quick, typically completed within 30 to 60 minutes, and provides valuable information to guide diagnosis and treatment decisions.
What to Expect on the Day of the CT Angiogram
Upon arrival, you'll be briefed about the procedure. A healthcare professional will insert an intravenous (IV) line to administer the contrast dye.
When you arrive at the imaging centre or hospital, a healthcare professional will check your vital signs and explain the procedure. You may be asked to avoid caffeine or certain medications prior to the scan to maintain a stable heart rate.
An intravenous (IV) line will be inserted into your arm to administer a contrast dye that helps highlight your blood vessels on the scan. In some cases, you may also receive medication to slow your heart rate for clearer images.
During the Procedure
You'll be asked to lie flat on a motorised table that slides into the CT scanner, a large doughnut-shaped machine. You must lie still, and the technician may ask you to hold your breath briefly as images are taken.
As the contrast dye is injected through the IV, you may feel a warm sensation throughout your body. This is normal and temporary.
The entire scan usually takes about 10–15 minutes. The imaging process itself is very fast, although preparation may take a bit longer.
After the Procedure
Most patients can resume their regular activities immediately after the scan. You might be asked to stay briefly for observation, especially if you received heart-rate-lowering medication.
Drinking plenty of fluids over the next 24 hours is advised to help flush the contrast dye from your system and support kidney function.
The CTCA results are typically reviewed by a cardiologist or radiologist. Your doctor will go over the findings with you in a follow-up appointment and recommend next steps, if any, based on the results.
Benefits of CT Coronary Angiogram
A CT Coronary Angiogram (CTCA) is a highly effective, non-invasive imaging test used to visualise the coronary arteries and detect blockages or narrowing caused by plaque buildup. Here’s a closer look at its key advantages:
Unlike traditional coronary angiography, which requires inserting a catheter through the groin or wrist into the coronary arteries, a CT Coronary Angiogram is completely non-invasive. It uses a simple intravenous line (IV) to inject contrast dye and captures images using a CT scanner.
The entire scan usually takes less than 30 minutes, and the imaging process itself lasts just a few seconds. The preparation and post-procedure time are minimal, allowing patients to return to their normal activities shortly afterwards.
CT Coronary Angiography provides high-resolution, 3D images of the coronary arteries, heart chambers, and surrounding structures. These images can accurately detect even small blockages or abnormalities.
Early Detection of Heart Disease
CTCA can identify coronary artery narrowing or plaque buildup before symptoms such as chest pain or shortness of breath even appear.
Because CTCA is an outpatient procedure, there is no need for overnight hospitalisation or long recovery times. Most patients can go home shortly after the scan.
CT Coronary Angiography is generally considered low-risk, especially when compared to invasive catheter-based angiography. It’s particularly beneficial for low to moderate-risk patients, those with atypical symptoms, or those for whom invasive procedures pose additional health risks.
Benefit | Explanation |
Non-invasive | No catheter insertion, reducing infection risk |
Quick and Painless | Typically completed within 30 minutes |
Detailed Imaging | High-resolution 3D images of coronary arteries |
Early Detection | Detects blockages before symptoms worsen |
Reduced Hospital Stay | Often done outpatient with minimal recovery time |
Safe for Most Patients | Lower risk than invasive angiography |
Risks and Limitations of CT Coronary Angiogram
While CTCA is generally safe, it has some risks and limitations:
Exposure to ionizing radiation (though minimal with modern scanners)
Allergic reactions to contrast dye in rare cases
Less effective in patients with very high heart rates or severe artery calcification
Cannot be used in patients with certain kidney conditions
CT Coronary Angiogram vs. Traditional Angiography
Feature | CT Coronary Angiogram | Traditional Coronary Angiography |
Procedure Type | Non-invasive | Invasive (catheter insertion) |
Procedure Time | 10–30 minutes | 30 minutes to 1 hour |
Recovery Time | Minimal, often outpatient | Several hours to days |
Risks | Low (radiation + contrast risks) | Higher (bleeding, infection, artery damage) |
Visualization | Coronary artery lumen and wall | Coronary artery lumen only |
Preparing for Your CT Coronary Angiogram
Follow fasting instructions, usually 4-6 hours before the test
Avoid caffeine and smoking on the day of the test
Inform your doctor if you have allergies or kidney problems
Wear comfortable clothing and remove metal objects

What Happens After the Test?
Post-procedure, you can resume normal activities immediately unless advised otherwise by your doctor. The radiologist will analyze the images and send a detailed report to your cardiologist, who will discuss the findings and recommend further treatment if necessary.
