摘要
随着我国人口老龄化趋势不断上升,冠心病患病率随之提升,好发于60周岁以上老年患者。冠心病又称为冠状动脉粥样硬化性心脏病,具有较高的致残率、致死率。随着医学影像技术不断成熟,CT因无创、扫描快的优势已经在临床中得到广泛推广应用,成为了诊断疾病的主要方法之一。CT可分为64排螺旋CT、DSCT、320DVCT,使得正确诊断冠状动脉疾病率得到很大的提升,为无创性检查和评估冠心病提供有效的依据。据有关研究报道,冠状动脉血管成像(CTA)假阳性、假阴性提升的主要原因为患者心率不齐、心率过速造成为心脏运动轨迹伪影;冠状动脉壁管存在钙化伪影均是其主要原因。因此临床常重点关注钙化伪影、心脏运动轨迹伪影对诊断准确性的影响。本文主要就CTA在冠状动脉钙化斑块管腔狭窄诊断中的价值进行综述。
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.
