What it is and how it works: A cardiac CT is an investigation that uses x-rays to take detailed images of the heart. Unlike a chest x-ray, which produces a 2D image, a cardiac CT produces a 3D image. When a cardiac CT test is used to evaluate the arteries that supply blood to the heart, this is called a CT coronary angiogram – a specialized type of CT test. This can help to identify any narrowing or blockages (coronary artery disease) that might be the cause of your symptoms.
What it detects: A cardiac CT can be requested to help investigate certain problems of the heart, such as congenital heart disease, valve defects, blood clots, tumors, or a buildup of lipid plaque in the arteries that surround the heart.
