CT Coronary Angiography is a non-invasive imaging method that employs X-rays and a contrast dye to produce detailed 3D images of the coronary arteries. This technique enables us to see plaque accumulation and blockages that may contribute to heart disease. It is especially beneficial for individuals who are experiencing chest pain, have risk factors for Coronary Artery Disease, or need a non-invasive option instead of traditional angiography. This service offers a clear view of the coronary arteries, allowing us to identify potential issues early and determine the next course of treatment.
Procedure Overview
During a CT Coronary Angiography, you’ll lie on a table that slides into a CT scanner. Before the scan, a small intravenous (IV) line will be placed to administer a contrast dye. This dye helps highlight the coronary arteries in the images. You may also receive medication to slow your heart rate, ensuring clear images. The scanner rotates around you, taking multiple X-ray images. These images are then processed by a computer to create detailed 3D reconstructions of your coronary arteries. The procedure typically takes between 10 to 15 minutes. We utilise advanced multi-detector CT scanners that offer high-resolution images and minimise radiation exposure.
Benefits & Importance
CT Coronary Angiography offers several advantages over traditional invasive angiography. It’s a non-invasive procedure, meaning no catheters are inserted into your arteries, reducing the risk of complications. It provides a comprehensive view of the coronary arteries, allowing for early detection of plaque buildup and blockages. This early detection enables timely intervention, preventing heart attacks and improving long-term heart health. By providing detailed anatomical information, it helps guide treatment decisions and avoid unnecessary invasive procedures.
Preparation & Requirements
It’s essential to inform us about any allergies, especially to iodine or contrast dye. You’ll also need to disclose any medications you’re taking. During the procedure, you may experience a warm sensation or a metallic taste after the contrast dye injection. After the scan, you can usually resume your normal activities. We recommend staying hydrated to help flush the contrast dye from your system.
Risks & Considerations
While CT Coronary Angiography is generally safe, there are potential risks associated with the contrast dye, including allergic reactions and kidney problems. The radiation exposure from the CT scan is also a consideration, although modern scanners use low-dose techniques. The procedure is not recommended for pregnant women. Individuals with severe kidney disease or uncontrolled hyperthyroidism may also have contraindications. It’s important to discuss your medical history and any concerns with your doctor to ensure the procedure is suitable for you.
Understanding the health of your coronary arteries is vital for preventing heart disease. A CT coronary angiography offers a non-invasive and accurate way to assess your risk and guide treatment decisions. If you’re experiencing chest pain, have risk factors for heart disease, or need a non-invasive alternative to traditional angiography, don’t hesitate.
