CT Coronary Angiography - Dynamic X-Ray of the Heart in Melbourne
A computed tomography (CT) coronary angiogram is a non-invasive imaging test that visualises the coronary arteries that sit on the heart muscle which supply blood to your heart.
It is usually performed to determine whether your coronary arteries are narrowed or blocked as a result of fatty cholesterol plaque in the artery walls, which could explain the presence of chest pain or other acute or chronic symptoms. The CT coronary angiogram takes dynamic x-ray pictures of the heart. It checks for blockages or narrowing of the coronary arteries, as well as abnormalities of the heart muscle or heart valves. A CT coronary angiogram relies on CT imaging to construct high-resolution, three-dimensional images of your heart and its adjacent coronary arteries after intravenous dye (contrast) is inserted into your arm via an intravenous line. This test is non-invasive, meaning it differs from a traditional invasive coronary angiogram (an invasive coronary angiogram requires a cardiac catheter to be threaded inside the body via the wrist or groin artery until it reaches the coronary arteries of the heart).
