CT coronary angiography classification

CT coronary angiography classification involves assessing the coronary arteries' health using advanced imaging. It categorizes the degree of artery narrowing (stenosis) caused by plaque buildup: normal (no narrowing), minimal, mild, moderate, or severe. This helps doctors determine the risk of heart problems and guides treatment decisions. The classification is based on how much the artery's lumen (inner open space) is blocked—less than 50% narrowing is usually mild, while over 70% indicates a more significant obstruction. This system provides a structured way to evaluate coronary artery health non-invasively, aiding in diagnosis and management of coronary artery disease.
