Role of coronary CT imaging diagnosis of coronary functional stenosis

Abstract

Coronary heart disease is a major disease harmful to human health, and coronary angiography, as the gold standard for the diagnosis of coronary heart disease, can directly observe the degree of coronary artery diameter stenosis. However, the invasive and expensive cost of coronary angiography limits its clinical application, and some studies have shown that coronary anatomical stenosis can not fully reflect the myocardial ischemia, and put forward the concept of functional stenosis. With the development of CT technology, coronary artery CT angiography has become a new method to detect functional stenosis. This paper reviews the role of coronary artery CT angiography in the detection of functional coronary artery stenosis.
