冠心病的诊断是临床诊治的第一步。随着医学影像技术硬、软件的飞速发展,CT冠状动脉成像成为现实,实现了冠状动脉无创造影检查。CT冠状动脉造影在冠状动脉狭窄判断、斑块诊断、钙化积分测定、冠状动脉支架置人术后评价及左室心功能分析等方面发挥重要作用,在一定范围内可代替常规冠状动脉造影。该文对多层螺旋CT冠状动脉造影检查在冠心病诊断中应用进行分析。 Coronary heart disease diagnosis is the first step in clinical diagnosis and treatment. With the rapid development of medical imaging technology and software, CT coronary angiography has become a reality, achieving coronary noninvasive imaging. CT coronary angiography in the judgment of coronary stenosis, plaque diagnosis, calcification score, postoperative coronary artery stent placement and left ventricular function analysis plays an important role, in a certain range to replace conventional coronary angiography. This article analyzes the application of multislice spiral CT coronary angiography in the diagnosis of coronary heart disease.
