64排螺旋CT是诊断冠心病的新手段,其最大的优点是无创伤,病人只需静脉内注射60~80毫升显影剂,就可以清晰显示冠状动脉的立体影像。64排螺旋CT冠状动脉成像的研究表明,64排螺旋CT诊断冠状动脉>50%狭窄的敏感性为95%,特异性为93%。64排螺旋CT除无创性,还有使用造影剂比冠状动脉造影少、价格低等优点,正成为临床检查、评估冠状动脉粥样硬化发生、发展及病变程度的常用检查手段。
64-slice spiral CT is a new method to diagnose coronary heart disease. Its biggest advantage is noninvasive. Patients can clearly show the 3D images of coronary arteries by intravenous injection of 60 ~ 80 ml of contrast agent. 64-slice spiral CT coronary angiography studies have shown that 64-slice spiral CT diagnosis of coronary stenosis> 50% of the sensitivity was 95%, the specificity was 93%. In addition to non-invasive 64-slice spiral CT, and the use of contrast media less than coronary angiography, the advantages of low prices, is becoming a clinical examination to assess the occurrence of coronary atherosclerosis, development and degree of disease commonly used means of inspection.
