CT Angiogram and Heart Health: How Advanced Imaging Can Assess Your Coronary Arteries. (02) 8315 829
Author : crystal radiology | Published On : 22 Sep 2026
Heart disease remains a major health concern worldwide, and coronary artery disease (CAD) is one of the most common conditions affecting the heart and blood vessels. It develops when plaque builds up inside the coronary arteries, which supply oxygen-rich blood to the heart muscle. Over time, this narrowing can reduce blood flow and may increase the risk of serious cardiovascular problems.
Advances in medical imaging have made it possible to assess the heart and coronary arteries using non-invasive techniques. Get CT Angiogram at Crystal Radiology to explore how advanced CT imaging may help your doctor assess your coronary arteries and understand your cardiovascular health.
What Is a CT Coronary Angiogram?
A CT coronary angiogram, also known as coronary CT angiography (CCTA), is a specialised CT scan that creates detailed images of the coronary arteries. Unlike traditional angiography, which requires a catheter to be inserted into a blood vessel, CCTA is non-invasive.
During the examination, a CT scanner captures multiple images of the heart while it is beating. In many cases, contrast material is injected into a vein to make the coronary arteries easier to see.
The images can help doctors assess:
- The condition and structure of the coronary arteries
- Areas where arteries may be narrowed
- Plaque within the coronary arteries
- The presence of significant coronary artery disease
- Other structural features of the heart and nearby blood vessels
Get CT Angiogram at Crystal Radiology when your referring doctor believes detailed imaging of your coronary arteries may help investigate symptoms or assess cardiovascular risk.
Can a CT Angiogram Tell You Your Heart Score?
The term “heart score” can refer to different forms of cardiovascular risk assessment, so it is important to understand the difference between a CT coronary angiogram and a coronary artery calcium score.
A coronary artery calcium (CAC) score is obtained through a specialised CT scan that measures calcified plaque in the coronary arteries. The result provides a numerical score based on the amount of calcium detected.
A higher calcium score generally indicates a greater amount of calcified plaque and can be associated with a higher risk of coronary artery disease. However, a calcium score does not provide the same information as a CT coronary angiogram.
A CT coronary angiogram can provide more detailed anatomical information about the coronary arteries, including the presence and characteristics of plaque and areas of narrowing.
Your doctor can determine whether a calcium score, CT coronary angiogram, or another cardiovascular assessment is appropriate for you.
How Does a CT Coronary Angiogram Work?
A CT coronary angiogram uses advanced X-ray technology and computer processing to create detailed cross-sectional images of your heart and coronary arteries.
Before the scan, your heart rate may be checked. Depending on your circumstances, medication may sometimes be used to help control your heart rate so that clearer images can be obtained.
During the scan:
- You will usually lie on a CT scanning table.
- Electrodes may be placed on your chest to monitor your heartbeat.
- An intravenous line may be inserted if contrast is required.
- You will be positioned inside the CT scanner.
- You may be asked to hold your breath briefly while images are acquired.
- The CT scanner creates detailed images for assessment by a qualified medical professional.
The scan itself is generally quick, although the overall appointment may take longer because of preparation and monitoring.
Is a CT Angiogram Safe?
CT imaging uses X-rays, meaning there is exposure to ionising radiation. Medical imaging providers use protocols designed to obtain the necessary diagnostic information while managing radiation exposure.
If contrast material is required, you should tell your healthcare team about any previous reactions to contrast, kidney problems, allergies or other relevant medical conditions.
Pregnant patients or those who may be pregnant should inform their doctor and imaging provider before undergoing CT imaging.
Your doctor and radiology team can explain the benefits and potential risks based on your individual circumstances.
