Abstract
As the trend of population aging in China continues to rise, the prevalence of coronary heart disease increases, and it occurs in elderly patients over 60 years of age. Coronary heart disease, also known as coronary atherosclerotic heart disease, has a high rate of disability and mortality.With the continuous maturity of medical imaging technology, CT has been widely used in clinical practice because of its advantages of non-invasive and rapid scanning, and has become one of the main methods for diagnosing diseases. CT can be divided into 64-row spiral CT, DSCT, 320 DVCT, which makes the diagnosis of coronary artery disease rate greatly improved, and provides an effective basis for non-invasive examination and evaluation of coronary heart disease. According to relevant research reports, the main reason for the increase of false positive and false negative in coronary angiography (CTA) is the heart motion trajectory caused by abnormal heart rate and heart rate tachycardia; calcification artifacts in coronary artery wall are the main reasons. Therefore, the clinical focus is often on the impact of calcification artifacts and cardiac motion trajectory artifacts on diagnostic accuracy. This article reviews the value of CTA in the diagnosis of coronary calcification plaque stenosis.关键词
